高原山区复杂地质条件下高档普采技术应用

摘要

柳树青煤矿井下地质构造复杂，属典型的云贵高原复杂地质构造，与北方煤层条件比较，煤层起伏变化较大，断层褶皱构造较多，对于高档普采技术的应用与推广具有一定的难度，本文在柳树青煤矿11502采煤工作面进行高档普采应用，针对复杂地质条件进行系统优化与技术改进，实现安全、高效开采，为类似条件工作面的安全回采提供了经验。%The underground of Liushuqing coal mine is complicated,which belong to typical complicated yunnan-guizhou plateau geological conditions,compared with coal stem in north area,the fluctuations and changes of stem are large and fold structure are more.Therefore there are difficulties in application and popularization of high-grade conventional mining technique.This thesis based on application of high-grade con-ventional mining on 11502 mining face at Liushuqing Coal Mine,which aim at system optimization and technological innovation under compli-cated geological condition,and to realize safe and productive mining,also provide some experience to safe extraction under similar condition.
