according to information available in belle ayr mine plans, dewater- ing of the coal seam in the mine area began in 1974 and dewatering of overburden deposits began in 1977. no dewatering on the caballo rojo lease area occurred during 1974-81. the commonly used method of dewater ing is to pump directly from the bottom of a mined pit.,environmental impact statement (eis) assessment report for,washpool coal pty ltd, a wholly owned subsidiary of aquila resources limited, is the proponent for the washpool coal mine project. the project would involve the development of an open cut pit, mining up to 7.2 million tonnes a year (mt/y) of run-of-mine (rom) coal to produce approximately 2.6 mt/y of coking coal
surface mining is generally considered to provide better recovery, grade control, flexibility, safety, and working environmen ts than underground mining. figure 3 shows a comparison of the total injury rates in us coal mines. the injury rates have declined both in surface and underground mines. however, the total number of injuries per one million,dewatering ultrafine slurries,illinois coal mines produced 52.1 million tons of coal in 2013. direct employment: 4,000; indirect employment: 12,000 typical waste production from coal mining varies from 10-50%. ultrafine waste material of the order of 10%. disposal/lifetime liability increasingly a bottleneck. beneficial reuse of dewatered coal mine waste
