Strata controlling of gob-side entry in fully-mechanized mining with top-coal caving face

本文通过现场观测 ,分析了综放面沿空巷道的围岩稳定性 ,并指出了控制围岩稳定性的技术关键 ,对几种围岩控制方法进行了比较 。

Based on field observations, this paper analyzes the strata stability around gob side entry in fully mechanized mining with top coal caving face. The technological key for controlling of strata stability is also indicated. After comparing the differences of several methods for strata controlling, this paper points out that bolting has broad prospect around gob side entry in fully mechanized mining with top coal caving face.
