Mining Impacts of Coal Seam Group Mining on Adjacent Roadways in Coal Seam
The spatio - temporal relationship of pressure behavior in coal seam group mining is complex , and it is so difficult to maintain the roadway.The ground pressure control is one of the basic theories of underground coal mining, and its important basis for mining roadway layout in the design, selection and support.According to the geological and engineering conditions of QianJiaYing mine close range coal seam group mining, and the results of long - term research of ground pressure, the stress distribution around the stope is analyzed.The superposition of high stress formed by multiple - coal strata mining is explored and caused the damage to coal seam roadway, and it provided the underground pressure basis for coal seam group mining design.
