摘要
就济宁三号煤矿163下00工作面沿采空区回采、沿"梯形煤柱"开采、向大断层推进、面向采空区开采等复杂条件下冲击地压危险性进行分析,根据不同条件采取针对性防治技术措施,实现了工作面的安全回采。
An analysis is carried out on the dangers of pressure bump resulting trom coal mining along gob area, coal mining along ＂ ladder--shaped＂ coal pillars, mining towards big faults and mining towards gob areas in the 163 lower 00 coal face under complicated geological conditions in Jining No. 3 coal mine. This paper also reveals that in this case, appropriate preventive and control measures are taken according to various conditions, which realizes safe mining at the coal face.
