大采高综采工作面应用错层位巷道布置法的探讨

Discussion of Stagger Arrangement Roadway Layouts Methods Applied in Fully Mechanized Working Face of Thinner Thick Coal Seam

为提高煤炭采出率,解决厚煤层大采高综采工作面存在的端头三角煤损和区段煤柱问题,依据相关理论研究和生产实际,根据顾桥矿13-1煤层的实际赋存特点,对厚煤层应用错层位巷道布置法进行无煤柱开采的可行性进行了探讨。

In order to enhance the recovery rate, solve the problem of end triangle coal loss and section pillar existed in the thinner thick seam, this paper According to the related theoretical research and preduetion practice, with the actual occurrence characteristics of 13 -1 coal seam in Guqiao coal mine as the background, discuss the possibility of stagger arrangement Roadway layouts methods without pillar applied in thinner thick coal seam.
