摘要
通过对平朔井工一矿4108综放工作面两柱掩护式放顶煤支架工作阻力的实测以及运用地震CT技术对该工作面超前支承压力的探测与分析,得出了该工作面的矿压规律,并对比相邻的4107工作面的矿压显现规律,为类似综放工作面安全高效回采提供依据。
Underground pressure behavior law is obtained by measuring the working resistance of two-leg shield caving support and applying seismic CT technology to detect and analyze the advance abutment pressure in 4108 fully mechanized caving face in Jinggong No.1 mine, Pingshuo. The results are compared with the underground pressure behavior law of 4107 caving face, which can provide basis for the similar caving face to mine efficiently.
