综采工作面初采阶段关键技术探讨

Discussion on Key Technologies in the Initial Mining Stage of Fully Mechanized Mining Face

初采在综采工作面回采过程中出现的问题最多,其中,顶板是最主要的影响因素,出现的问题也最多。通过对初采历次出现的问题进行分析,找出了减少乃至消除影响的共性措施和办法,以降低综采工作面初次来压对工作面的破坏程度,为工作面快速、安全、高效地推进提供技术指导。

The most problems occurred in the mining of fully mechanized mining face in the initial mining process. Roof is the most important factor, of which the most problems occur. Through the analysis of the problems that have occurred in the initial mining, this paper found common measures and methods to reduce or even eliminate the impact, so as to reduce the damage caused by the initial pressure on the working face of the fully mechanized mining face, and provide technical guidance for the quick, safe and efficient advance of the working face.
