摘 要:以古书院矿边角煤柱现状为基础,结合短壁综采煤柱工作面回采工艺,总结出边角煤柱资源最大采出率的理论计算公式。探索出的边角煤柱短壁综采工作面切眼对接施工技术,减少了对接施工成本,使边角煤柱综采工作面切眼对接施工安全顺利进行。According to the status quo of marginal coal pillar in Gushuyuan Coal Mine,combined with the extraction technology of short wall fully-mechanized mining face with coal pillar,the theoretical calculation formula of maximum recovery rate of marginal coal pillar was summarized in the paper. The cutting hole docking technology of short wall fully-mechanized mining face with coal pillar was applied into practice,and the cost of docking construction is reduced,the construction of short wall fully-mechanized mining face with coal pillar is safe and smoothy.
