水采工作面跨巷开采的矿压控制

The controlling of ground pressure with the method of over-the-roadway extraction in hydraulic coal mining face

介绍了水采工作面跨巷开采的矿压控制技术 ,并对水采跨巷矿压显现进行观测分析 ,与留设煤柱护巷进行了技术经济上的比较。

This article introduces the technique of ground pressure and its controlling with the method of over the roadway extraction in hydraulic coal mining face, analyzes the measurement behaviour of ground pressure. The roadway using the method of over the roadway extraction is also compared with those keeping pillar for roadway maintaining in this paper.
