摘要
山西兰花集团大阳煤矿是一座年产150万t的高产高效矿井,采区内无炭柱较多。随着矿井采煤机械化程度的提高,无炭柱对高效机械化生产的影响越来越大,通过加强顶板管理、改进采煤工艺、加强生产组织管理,完全可以实现含无炭柱综采放顶煤工作面的高效安全回采。以大阳煤矿3105综采放顶煤工作面为例,介绍了综放面平推过无炭柱条件下的顶板管理、开采工艺及生产组织管理等方面的成功经验。
Dayang coal mine is a high output and high efficiency mine with 1.5 million tons output per year. In this mining area there are many non-coal pillars with more and more effects on fully-mech- anized mining. The fully-mechanized mining face containing non-coal pillar can be mined effectively and securly by reinforcing roof control, improving mining technology and enhancing the producing organiza- tion. In this paper, the experience of roof control, mining technology and production organization and manage of directly passing non-coal pillar fully-mechanized mining face is introduced based on the example of 3105 fully-mechanized mining face of Dayang Coal mine.
