一、改革采区巷道布置的原因 采区巷道布置的合理与先进,是加快煤矿建设速度,缓和采掘接替紧张,提高技术经济效益的重要途径。从六十年代开始,我国的缓倾斜厚煤层或煤层群的采区巷道布置,由沿煤层分别布置,逐渐改为以采区底板岩石上下山和底板岩石集中巷(包括岩石中车场)为主体的布置方式,虽然使巷道的维护条件大大地改善了,但却带来了岩巷工程增大、采区准备时间增长、生产运输环节增多、矿井经营性亏损增加等问题,比较严重地限制了采区生产力的进一步发挥。
I. Reasons for reforming the layout of roadway in mining area Reasonable and advanced in the layout of roadway in mining area is an important way to speed up the construction of coal mines and ease the tension of mining to take over and improve the technical and economic benefits. Starting from the 1960s, the roadway layout in mining areas with gently inclined thick coal seams or coal seams in China has been gradually changed from coal seam along the coal seam to rock-dominated lanes (including rock car parks) The layout of the roadway has greatly improved the maintenance conditions of the roadway but has brought about such problems as the enlargement of rock and roadway engineering, the increase of the preparation time of the mining area, the increase of production and transportation links and the increase of operating loss of the mine, Mining area productivity further play.
