Blasting is an integral part of surface mining operations. To uncover coal reserves, the rocks overlying the coal are broken with explosives and excavated with various types of large earth-moving equipment. Without blasting, a vital part of the nation's energy reserve would be inaccessible. Blasting is one of the most frequent complaints received by OSMRE

The Surface Mining Control and Reclamation Act of 1977 (SMCRA) requires that coal mining be conducted in a manner that prevents injury to people and damage to public or private property during blasting. The side effects of blasting are

The most dangerous and apparent of these is flyrock. Injury or death to people and property damage may happen when a piece of rock is thrown beyond the permit boundary. The blaster is responsible for preventing flyrock and controlling ground vibration, airblast and fumes. OSMRE oversees the only national program to certify blasters. Training provided for blaster certification addresses the control of flyrock, vibrations, airblast and fumes by the appropriate use of explosives and hazard recognition in the field

Ground vibrations and airblast may cause people's homes to shake. When people feel their homes shake, they may associate damage to their homes as being a direct result of blasting at a surface coal mine. OSMRE blasting regulations limit the amount of ground vibration or airblast that arrives at homes for the purpose of preventing structure damage. Some coalfield citizens claim that the OSMRE regulations do not adequately protect their homes and property. OSMRE set limits based on scientific studies that reasonably protect most typical residential structures. When the blasting limits are exceeded, violations are written and action may be taken against the blaster’s certificate. Occasionally, damage to homes is possible at vibration levels below the limits, particularly when structures aren’t representative of typical structures (e.g. adobe, log, or mobile homes). In these situations, OSMRE and the States are responsible for investigating the damage claim and/or adjusting limits to prevent damage

blasting - office of surface mining reclamation and

If a home is damaged from a coal mine blast, a homeowner may receive compensation for or repair of the damage. Some property damage identified may pre-date the blasting and is caused by other natural factors (e.g., structure aging, poor foundation, normal stresses, runoff control, etc.) or improper construction. These damages are not the responsibility of the coal company

OSMRE recognizes that people are sensitive to blasting vibrations and can feel blasts that are as little as 2% of the legal vibration limits. Thus, blasting that shakes their homes, but is within legal limits, may often annoy people. Depending on person’s sensitivity, any given blast may be offensive. While OSMRE does not regulate this annoyance, the regulations do recognize that people need advance warning. To help minimize annoyance, the rules require warning signals (audible to residents within ½ mile) that alert the public of impending blasts. The meaning of the signals and the specific blasting times are provided in a blasting schedule notice that is mailed to residents within ½-mile of any blasting. Additionally, homeowners can ask questions about the blasting during the pre-blasting survey of their home (available to residents within ½ mile of coal mining permit boundaries)

cdc - mining - history of the mining program - niosh

This document describes the history of the mining research program, beginning with the establishment of the U.S. Bureau of Mines in 1910. It describes the evolution of the program and its accomplishments over the years, culminating in its transformation as the National Institute for Occupational Safety and Health in 1996 and the establishment of the National Personal Protective Technology Laboratory in 2001

For years prior to 1910, there were calls from many quarters to create in the federal government a bureau that would collect, evaluate, and disseminate scientific, technologic, and economic data of value to the mineral industries. The American Mining Congress, for example, proposed the creation of a federal Department of Mines at its 1896 annual convention. The conservation movement also envisioned a federal role in helping the nation use its mineral resources responsibly. Concern over the waste of both human and natural resources was reflected in President Theodore Roosevelt's recommendation in 1907 to establish a U.S. Bureau of Mines (USBM) in the Department of the Interior. Congress, however, did not act on this until a series of disasters in the nation's coal mines focused public attention on the loss of human life. These disasters took more than 3,000 lives in 1907 alone. There were 361 coal miners killed in Monongah, WV, on December 6, 1907; 239 killed two weeks later at Jacobs Creek, PA; 154 killed at Marianna, PA, on November 28, 1908; and 259 killed at Cherry, IL, on November 13, 1909

The U.S. Geological Survey (USGS) of the Interior Department earlier had established a close relationship with the mining and mineral industries through the preparation and publication of its annual report on Mineral Industries of the United States. The USGS was also conducting studies in important mining areas. In 1899, the USGS Director recommended establishing a Division of Mines and Mining and, in 1904, Congress appropriated funds for analyzing and testing the coals of the United States. This led to the formation of the technologic branch, headed by Dr. Joseph A. Holmes, a former North Carolina state geologist and university professor. On May 16, 1910, Congress passed the Organic Act (Public Law 61-179) establishing the USBM. The act authorized the Secretary of the Interior to transfer to the new bureau the types of investigations heretofore conducted by the technologic branch of the USGS together with the pertinent personnel, equipment, and property. The USBM became functional on July 1, 1910. Shortly thereafter, Dr. Holmes was appointed its first director and served until his death in July 1915

The original mission of the USBM was to provide the mining industry with information on blasting materials and techniques that could be used safely in the presence of flammable mine gases and dust. This meant identifying the chemical and physical characteristics that allowed explosives to perform usefully without initiating disastrous fires and explosions. These considerations defined the two main objectives of the USBM's initial research and development - safer blasting materials for underground coal mines, and prevention of underground mine gas and dust explosions

cdc - mining - history of the mining program - niosh

Although administratively headquartered in Washington, DC, the principal research activities were conducted by the Pittsburgh Mining Experiment Station under Dr. Holmes. According to the Organic Act, the USBM was, among other things, "to make diligent investigation of the methods of mining, especially in relation to the safety of miners, the use of explosives, the prevention of accidents." This reflects the origin of what eventually became known as the Pittsburgh Research Center

In establishing the USBM, Congress undoubtedly was mindful of similar test stations established earlier in England, Germany, Belgium, Austria, and France, whose work had done much to reduce the frequency and severity of coal mine accidents. Recognizing this, the Secretary of the Interior had requested a delegation of foreign experts to visit U.S. mines to make recommendations to improve safety and efficiency. Thus, the groundwork for the birth of the USBM had been laid

list of authorised explosives | resources safety & health

This document lists all explosives authorised by the Chief Inspector of Explosives under section 8 of the Explosives Act 1999. The list is designed to help people involved with managing explosives to identify authorised explosives. It is updated regularly. This version lists all explosives authorised up to 1 January 2021 and replaces the previous version 36 dated 1 July 2020

The Explosives Act requires that all explosives used in Queensland must be authorised by the Chief Inspector of Explosives, and that a register of authorised explosives be maintained and made available to anyone requesting it. Explosives compositions and articles may also be authorised

The Act does not require explosives to be authorised for particular purposes. These details are provided by the manufacturer as the manufacturer's recommendations for the conditions of use as provided through the quality and character of the explosives

Permitted explosives form a special class of explosive authorised for use in underground coal mines. Explosives designed for use in underground coal mines must be tested as a permitted explosive against the criteria of the UK Health and Safety Executive testing memorandum TM2. Within Queensland, TM2 is the only accepted specification for explosives used in underground coal mines. TM2 groups explosives in relation to their intended use as follows:

list of authorised explosives | resources safety & health

Permitted explosives are authorised through a request to the Chief Inspector under section 13 of the Explosives Regulation 2017. They are authorised as suitable for use in an underground coal mine only in relation to their intended use in P1–P5 applications. For further information, refer to Explosives Information Bulletin 10 Authorisation of explosives and trials of unauthorised explosives

Further restrictions apply to the use of permitted explosives. The maximum charge limit for a P1 or P3 permitted explosive allowed in any one shot hole shall not exceed 800 grams. The quantity used in a single shot hole may be increased, subject to a site specific risk assessment, to a maximum of 1200 grams,provided that the shot hole is more than 1.8 metres in length with a minimum burden of 0.5 metres with at least 0.6 metres of stemming. For multiple shot holes, no more than 1600 grams. The maximum charge weight for a P5 permitted explosive allowed in one shot hole shall not exceed 1000 grams.Refer to the Coal Mines Inspectorate and the manufacturer for further information
