摘要
现有的大倾角厚煤层开采技术存在着一系列问题,从而导致煤矿回采率低,安全性差,成本高。针对这一情况,提出改革大倾角厚煤层巷道布置及回采工艺,以解决目前实际生产中存在的一些技术难题。
There are series problems exist in the existing thick seam mining technology with large dip angle, thus cause low extraction rate, poor safety and high cost. Aiming at this condition, reform roadway arrangement and extraction process in large dip angle thick seam is put forward to solve some technical problems exist in practical production.
