Feasibility analysis on 1300 fully-mechanized coal mining face of Jining No.2 Mine during exploitation approaching to faults and its optimization design

摘要

The primary influence factors of layout of 1300 fully-mechanized coal mining face are Balipu Fault, F24 Fault and the accumulated water in mined-out areas of No. 1 Mine Area in Jining No.2 Mine. According to the analysis of geology and hydrographical geology of the mining area, and combined with "Water Prevention Regulation of Coal Mines" and related achievements in scientific research, the mining feasibility of 1300 fullymechanized coal mining face was studied. Through economy comparison, the design of mining stope and water prevention was optimized, 0.8 million tons coal resource can be recovered.
