综采工作面巷道超前支架适应性及选型分析

Adaptability and Lectotype Analysis on Forepoling Support for Entries of Fully Mechanized Coal Mining Face Roadway

根据潞安集团李村煤矿的地质情况和采煤工艺等实际条件,选用适合的巷道超前支架,解决了煤矿综采工作面运输和回风巷道出口20 m处的超前机械化支护,保证了在复杂的地质条件下工作面巷道的安全稳定性,为煤矿实现安全、高效生产提供重要的前提和保障。

According the actual geological and mining technology conditions of Lian Coal Mine, Lu＇ an Group, a suitable forepoling support was selected to solve the mechanization problem of forepoling at exports, which was extending for 20 m in the headentry and the tailentry of a fully-mechanized coal mining face. The support can ensure the security and the stability of the entries under complex geological conditions, which offering an important premise and guarantee for realizing safe and high efficient production of the coal mine.
