缓倾斜煤层综采面旋转开采方法

由于地质条件等因素的影响,综采工作面的推进长度较小,影响工作面的高产高效.本文提出了在缓倾斜煤层综采工作面采用倾斜长壁与走向长壁混合布置,工作面旋转开采,加大了工作面的推进长度.分析了其巷道布置及其特点,为特殊条件下工作面高产高效提供了一条途径.

Rotating mining method at slowly inclined seam's comprehensive mining coal face

High production and high efficiency at the comprehensive mining coal face are a development trend of coal industry. Influenced by geological conditions and other factors, the advancing length of the coal face is very small, thus affect high production and efficiency at the coal face. This paper suggests mixing inclined long wall with vertical long wall at the slowly inclined seam's comprehensive mining coal face and mining with rotating the coal face so as to increase the advancing length of the coal face. It also analyses the distribution and characteristics of tunnels and offer a way of high production and efficiency under special conditions.
