摘要
2319、2321和2313大倾角工作面顺槽和切眼布置在230采区西翼,工作面沿断层展布方向呈伪倾斜布置,工作面均为俯采综放工作面,顺槽和切眼均为上山掘进,顺槽最大坡度35°,切眼最大坡度45°,顺槽和切眼均沿煤层底板掘进。
This article intruced 2309,2321,2313 and so on in great inclination angle wonking surface constrution,facing the contraction difficulty and the risky all quite big situation,adopts some effective fast security construction technology,through these method utilization,had guaranteed the construction period security is fast.
