Study on the Evolution Law of Mining Coal Permeability
The high strength mining, fully mechanized sub-level caving method etc., have vital role to the gas permeable evolution in coal body. Taking the coal seam contained gas as subject to investigate under high strength mining condition, use the mining coal permeability real-time monitoring system monitoring the changes. We had conducted the research about coal permeability evolved rules in typical high gas, sick seam and high strength mining conditions. Through site test confirmation, the real-time monitoring system for mining coal permeability has certain validity and usability to coal permeability monitoring. The coal permeability of working field present increase, reduce and then elevate along with high strength mining. Quantitative coal permeability is basis of fully mechanized sub-level caving mining field gas disasters control and management.
