#0183;#32;The immediate roof and floor lithology are extremely important along with the bottom of coal elevation. Detailed geologic descriptions, including any features that would strengthen or weaken the lithology should be kept within at least 15 m above the coal for typical gobforming heights .

From 1991 through 1995, 44 miners out of a total work force of less than 2,000 were fatally injured in the stone industry. Of these, 12 occurred at underground mining operations with nine deaths resulting from roof or rib falls. A safer environment can be achieved by evaluating the nature of the hazardous ground and by developing more efficient and
Other Geologic Hazards Methane Gas Migration. In some areas of Pennsylvania (especially areas of coal mining and gas well activity), stray methane gas in the subsurface can be a hazard. Under certain conditions, methane can migrate to private watersupply wells and ultimately into a house or structure.
The underground coal miner faces a continuing hazard from the fall of roof. At the root of many injuries and fatalities are weak or defective roof strata . Throughout mining history, millions of miles of entry have provided exposure of every conceivable geologic
A simplified classification of the major hazardrelated geologic phenomena and the hazards they cause is presented in the box below. This chapter focuses on the use of information about earthquakes and earthquakeinduced landslides, volcanic eruptions, and tsunamis (ocean waves caused by earth movement) to improve development planning in Latin America and the Caribbean.
Throughout mining history, millions of miles of entry have provided exposure of every conceivable geologic roof hazard. This report describes the geologic origin, association, and potential danger from the most common hazards. Discussions of weak rock include drawrock, rider coals, head coal, stackrock, and stream valley effects. Discontinuities, or roof defects, are described including, clay veins, slickensides,
#0183;#32;The underground mine worker faces a continuing hazard from roof falls and other ground control related hazards. Many injuries and fatalities are related to mine roof that is weakened as a result of geologic factors. The roof may consist of rock that is inherently low in strength such as drawrock, thinly bedded rock, or mudstone.
Throughout mining history, millions of miles of entry have provided exposure of every conceivable geologic roof hazard. This report describes the geologic origin, association, and potential danger from the most common hazards.

A NIOSH report regarding the geologic hazards underground coal miners continue to face from the continuing hazards associated with roof stability. This report describes the geologic origin, association, and potential danger from the most common hazards. Discussions of weak rock included rawrock, rider coals, head coal, stackrock, and stream valley effects.
