vibration studies which became the accepted reference in the blasting field <strong>and</strong> are the<br />

basis for many state blasting codes, mine waste disposal studies which established the<br />

engineering basis for waste embankment regulation under the <strong>Health</strong> <strong>and</strong> <strong>Safety</strong> Act, the<br />

microseismic work which locates incipient rock bursts, the distressing studies which may<br />

someday prevent rock bursts, a low-cost acid mine water treatment technique, model<br />

studies which led to new concepts in the design <strong>of</strong> mine pillars <strong>and</strong> mine pillar<br />

reinforcement, <strong>and</strong> in-mine studies <strong>of</strong> pillar strength which will permit smaller mine<br />

pillars <strong>and</strong> greater productivity without sacrificing safety [USBM 1973].<br />

The work done under Explosives <strong>and</strong> Explosions <strong>Research</strong> was intended to improve the safety<br />

<strong>and</strong> efficiency <strong>of</strong> explosives used in mining, to provide maximum safety in their production <strong>and</strong><br />

h<strong>and</strong>ling, <strong>and</strong> to prevent accidental fires <strong>and</strong> explosions. Some <strong>of</strong> the functions <strong>of</strong> this work<br />

included:<br />

• Administering federal regulations for certification <strong>of</strong> permissible explosives.<br />

• Conducting basic <strong>and</strong> applied research to underst<strong>and</strong> explosion processes.<br />

• Developing practical methods to prevent <strong>and</strong> control mine fires.<br />

• Providing consultation on explosions <strong>and</strong> on safe use <strong>of</strong> explosives to other government<br />

agencies <strong>and</strong> industry.<br />

Some <strong>of</strong> the previous accomplishments cited for this Bureau program were:<br />

• Development <strong>of</strong> the new permissible explosives <strong>and</strong> testing procedures for these<br />

explosives that had greatly improved the safety <strong>of</strong> blasting with explosives in mines.<br />

• Recommendations for storage, transport, <strong>and</strong> utilization <strong>of</strong> blasting agents <strong>and</strong> hazardous<br />

chemicals that had received national <strong>and</strong> international recognition, including a recent<br />

study for the U.S. Coast Guard <strong>of</strong> hazards from spills <strong>of</strong> liquefied natural gas.<br />

• Development <strong>of</strong> a theoretical model <strong>of</strong> the detonation mechanism that had helped make<br />

the Bureau a world authority in the field <strong>of</strong> explosives research.<br />

Some <strong>of</strong> the previous accomplishments cited for <strong>Health</strong> <strong>and</strong> <strong>Safety</strong> <strong>Research</strong> were:<br />

• Studies on dust collectors, wetting agents, <strong>and</strong> foams for respirable dust control.<br />

• Use <strong>of</strong> vertical drainage holes for methane control.<br />

• Techniques for drilling <strong>and</strong> packing horizontal holes in coalbeds to help measure <strong>and</strong><br />

control methane.<br />

• Technology for design <strong>and</strong> evaluation <strong>of</strong> ro<strong>of</strong> control plans for mines using ro<strong>of</strong> bolts for<br />

support.<br />

• Lighting studies to provide the basis for proposed m<strong>and</strong>atory illumination st<strong>and</strong>ards.<br />

• A number <strong>of</strong> devices developed for improved safety in underground coal mines.<br />

The funds appropriated to the Bureau by Congress for fiscal year 1973 totaled $157 million.<br />

This funding can be broken out into the following areas:<br />

• <strong>Health</strong> <strong>and</strong> safety enforcement—$64 million<br />

• Energy-related research—$20 million<br />
