资源整合矿井沙坪煤矿开拓方案的确定

综合分析了井田内原有小煤窑的巷道及采空区分布对将来的影响,提出了两个开拓方案。并对两个方案进行初步的技术经济对比,最终选择了改造利用资源整合小窑之一的火山煤矿现有主斜井和材料平峒,尽量增大综采工作面的推进长度,有效避免了原采空区对矿井生产的影响,确保了矿井的高产高效,取得了良好的经济效益。

Mine Development Scheme on Resource Integration in Shaping Mine

The study examines the influence on the future from roadways and mined-out areas of previous small mines and proposes two development schemes.The two schemes are compared preliminarily at the point of technology and economy.Finally,we choose to use existing inclined shafts and material galleries of one mine.The driving length is enlarged as much as possible to avoid the influence of old mined-out areas on mining and to guarantee the high yield and high efficiency of mines,which has achieved better economic benefits.
