摘要
水力采煤适用于顶板稳定，沼气含量少，煤质中硬以下，倾角10～35°，煤厚3～8m，较复杂的地质构造。介绍了古韩联营煤矿利用水力采煤的工艺过程。
Hydraulic mining applied to roof stability, low gas content, the quality of coal below hardware, elevation angle 10 - 35 °, coal thickness 3 - 8 m, more complex geological structure. This paper introduced the technological process of using hydraulic mining in Guhan joint venture coal mine.
