留窄小煤柱沿空留巷在综采工作面的成功应用

The Successful Application of Gob-side Entry Retaining with Narrow and Small Pillars in Fully-mechanized Mining Face

通过窄小煤柱沿空留巷在综采工作面的成功应用,总结了一种沿空留巷开采方式,解决了受留巷影响综采工作面推进速度严重下降、沿空留巷推采时工作面与所留巷道之间通风行人困难、传统留巷方法所留设巷道受矿压影响破坏严重等问题。

Through the successful application of gob-side entry retaining with narrow and small pillars in fully mechanized mining face,a gob-side entry retaining mining method is summarized,which solves the problems of serious decline of the driving speed of fully mechanized mining face affected by the gob-side entry retaining,difficulty of ventilation and pedestrians between the working face and the remaining roadway during the gob-side entry retaining mining,and serious damage of the roadway retained by the traditional method of gob-side entry retaining.
