回采工作面过陷落柱采煤方法研究

Study on coal mining method of coal winning face passing through collapse column

陷落柱是煤矿开采过程中的一大安全隐患,直接影响井巷的开挖布置和采掘机械的选择。通过对某矿区3-802回采工作面地质构造、陷落柱发育、水文地质等因素进行分析,结合工程类比法,根据相同类型矿井过陷落柱的经验,针对3-802回采工作面过不同陷落柱采取不同的措施。

The collapse column is a hidden danger in the process of coal mining,which directly affects the excavation layout and the selection of mining machinery.Based on the analysis of geological structure,collapse column development,hydrogeology and other factors of 3-802 mining face in a mining area,combined with engineering analogy method,according to the experience of the same type of mine passing through the collapse column,different measures were taken for 3-802 coal winning face passing through different collapse columns.
