综放工作面高位裂隙钻孔优化布置

Optimization of the layout of higher position crack drill-holes in fully mechanized coal faces

通过对3008综放工作面高位裂隙钻孔布置的优化研究,确定了合理的钻场参数,解决了高瓦斯综放工作面瓦斯制约安全生产的难题,大幅度提高了工作面产量,认为该技术具有很好的社会、经济效益和应用前景。

Out of an optimization study on the arrangement of high position crack drill holes made in the No.3008 fully mechanized coal face,rationalized drill field parameters are determined.This solves the tough problem that work safety in the mine is always hindered by methane gas emission at coal faces.Per face coal output is increased by big margin.The author of this paper holds that this technology is of great social/economic benefit and it will have very good prospects in the future application.
