"HEALTH, SAFETY AND MINING TECHNOLOGY
The Health, Safety and Mining Technology (HSMT) program pursues fundamental scientific and engineering research in order to provide new technology to protect the Nation's miners, who are employed in one of the most hazardous of all occupations. Injuries and occupational diseases to workers are costly to the Nation in terms of compensation costs to current and future generations, economic growth in the raw materials sector of the economy, and the Nation's industrial competitiveness.
The research program focuses on solutions to the health and safety hazards that confront miners and other workers in the mineral sector of the economy, including exposure to dust, falls of roof, proximity to large equipment in confined space, and the potential for fires and explosions. This program also concentrates on long-range activities to devise new mining concepts that will safeguard miners with mechanisms that rapidly warn of, or suppress, hazards in advance of mining, thus enhancing productivity. Implicit in this program is the conservation of natural resources and environmental protection. The HSMT program is divided into seven research areas: Occupational Health, Ground Control, Human Factors, Mine Safety Systems, Mine Disaster Prevention, and Advanced Mining Systems.
Ground Control
The long-range goal of the Ground Control program is to produce technology to forecast impending catastrophic failure, maintain structurally sound and stable mine openings, and reduce injuries and fatalities caused by ground failure. The objectives of the Ground Control program include:
oDetermining the critical geological and geophysical criteria to be used to identify potentially unstable and hazardous zones in mines.
oDeveloping and demonstrating mine-wide monitoring systems to collect and analyze critical geomechanical and geophysical parameters in real time.
oDeveloping artificial support technology to enhance stability of the mine roof.
Enhanced efficiency in achieving Ground Control goals has occurred through consolidation of ground control technologies from two distinct, yet integrated, Ground Control subprograms-- geosensing and geocontrol. Technical products used within the geosensing subprogram will be integrated into operating systems to help miners detect imminent ground failures during active mining and delineate the structural and dynamic characteristics of the rock mass to allow implementation of effective controls. The geocontrol subprogram will focus on providing engineering solutions to mitigate or eliminate identified ground hazards.
Mine Safety Systems
The Mine Safety Systems program addresses the hazards to mine workers created by the operation and design of the physical systems that make up a modern mining operation. Today's mine is a very complex operation with large excavation equipment, fastmoving haulage vehicles, conveyor and hoist systems, high-voltage machinery, complex ventilation schemes, and sophisticated control and monitoring systems. Despite all of this mechanization, the mine worker is still the essential component in any mining operation. When these workers operate and interact with the mining machines in the harsh environments of underground or surface mines they are exposed to many hazards. These hazards historically are a factor in 55 percent of all mining fatalities and 25 percent of all mining injuries. To solve this problem, new technologies will be developed and applications of existing technologies will be pursued to remove or mitigate the safety hazard. The objectives of the Mine Safety Systems program are--
oTo reduce injuries resulting from mobile powered-haulage and transport equipment through modification of existing systems and the design of inherently safer systems.
oTo improve safety in the use of high-voltage power systems.
oTo reduce the injuries associated with the use and maintenance of the mechanical systems used in mines.
Mine Disaster Prevention
In mining, no other accident can have broader consequences than those involving fires, explosions, or outbursts of methane gas. Research under the Mine Disaster Prevention program strives to develop technologies and strategies that will either prevent the occurrence of these mine emergencies or enable miners to survive them. The program focuses on the avoidance or elimination of fires and explosions through early detection, containment, and suppression; the prediction, measurement, and removal of dangerous methane accumulations; the development of protective breathing equipment and efficient escape tactics; and the safe and optimal use of explosives. The objectives of the Mine Disaster Prevention program are to--
oDiminish mine worker exposure and vulnerability to the hazardous circumstances associated with fires and explosions.
oDesign reliable life-support apparatus and escape strategies for safe, expedient evacuation from mine emergencies.
oControl hazardous methane accumulations in all phases of underground mining.
oFurther the generation of safe and effective blasting practices and products for mining."
