Abstract:
Surrounding rock control problem in soft coal seam is the major problem which limited the development of coal mining, the specific performances include strong floor heave, large deformation of two sides, severe roof subsidence. Based on analyzing the principles that roadway support should follow, combining with the support engineering practice in 11011 haulage gate of Xinyi coal mine, U-type steel shed and anchor cable combined support technology which have controlled the soft coal roadway's stability well is adopted. The research results provides experience for solving roadway support problems of soft coal seam.
