摘要
为探究综采工作面进入末采阶段时超前区域矿压显现规律,本文以某矿209综采工作面为研究对象,通过在顺槽距停采线100 m位置设置煤体应力实时监测,得出综采工作面末采时对超前区域的压力影响范围,为综采工作面回撤安全通道提供补强支护依据,也为大巷保护煤柱留设提供理论依据。
In order to explore the law of mine pressure behavior in the advanced area when the fully mechanized mining face enters the final mining stage,this article takes the 209 fully mechanized mining face of a mine as the research object.By setting up the real-time monitoring of coal stress at the position of 100 m from the stop line of the roadway,and obtains the pressure influence range of the advanced area at the final mining of the fully mechanized mining face,which is firstly to provide a reinforcement support basis for the retraction safety channel of the fully mechanized mining face.,and secondly to provide a theoretical basis for the protection of coal columns in the main roadway..
