摘要
打通一矿新开辟采区瓦斯巷因断面大、排矸方式复杂,导致掘进速度慢,通过对南二区现瓦斯巷断面及排矸方式进行研究,优化瓦斯巷断面及排矸方式,加快了瓦斯巷掘进进度,缩短了掘进工期,加快了新采区工作面投产。
In the new mining area of the first coal mine, the section of gas lane is large and the way of discharging gangue is complex, which results in the slow tunnelling speed. Through the study of the section of the gas lane and the way of discharging gangue in the south second area, the gas lane section and the waste way are optimized, the progress of the tunneling is accelerated, the excavation time is shortened, and the production of the new mining area has been speeded up.
