Roadway supporting technology applied to three soft coal seam at Yanlong mining area in China
The compressive strength of coal in Yanlong mine area of China is less than 3 MPa. Basically, it is powdery. The roof and floor rocks are mudstone. Therefore, this coal seam is a typical “three soft” coal seam. Anchor and cable cannot be used due to low anchoring force. This paper describes how to s...
