义马矿务局甘豪煤矿位于河南省陕渑煤田南端,设计能力为6万t/年.该矿1984年12月简易投产后,采掘关系一直比较紧张.1989年初,全矿三个采煤队仅准备了两个长壁回采工作面,为解决接替问题,临时在井田北翼一、三采区之间圈出了一个可采储量2.0万t的小工作面——13181工作面,但这个工作面通风问题未获妥善解决.我们运用“受控循环通风”原理,成功地解决了13181工作面的供风不足问题,安全生产原煤近2万t,缓和了矿井采掘接替的紧张局面,现将我们的实践与体会作一介绍.
YMMA Mining Ganhao Coal Mine is located in the southern tip of Shaanxi Coalfield, Henan Province, with a designed capacity of 60,000 t / a. After the mine was put into operation in December 1984, the mining relationship has been quite tense. In early 1989, The team only prepared two long-wall mining face, in order to solve the problem of succession, temporarily in the minefield north of the first three mining area circle between the recoverable reserves of 20000 t small face - 13181 face, but The ventilation problem of this working face was not properly solved.We used the “controlled circulation ventilation” principle to successfully solve the problem of insufficient supply of wind on 13181 working face and safely produced nearly 20,000 tons of raw coal, easing the tense situation of mining extractions, Now our practice and experience to make an introduction.
