大倾角厚煤层条件下巷道布置改革的前景

The significance of innovating laneway layout in greater inclined and thick coal seams

现阶段,随着赋存条件"优越"煤层储量的减少,大倾角厚煤层开采逐渐得到重视。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。

At present, according to the reserves of the superiority coal seams is decreasing, more importance is attached to the greater inclined and thick seams. The present methods exist a series of problems, result in the low recovery percent, bad safety, high cost and so on. Aim at this instance, we put forward the innovation of laneway layout and mining thchnique in order to solve the problems in present coal mine production.
