靠帮开采“L”型内排压帮方式对敖包梁矿区的理论研究

Theory research on extracting along end slope L-type inner discharge pressure slope mode of Aobaoliang mining area

鄂尔多斯达拉特旗敖包梁地区分布着包括宝利露天煤矿在内的10多个中小型露天煤矿,普遍存在着开采秩序不合理,对端帮煤没有科学有效的开采,没有对边坡安全引起重视,未及时采取有效的压帮措施,造成边坡严重的安全隐患。所以针对包梁地区露天煤矿普遍存在的端帮开采问题做出相应理论方案,希望借此能对周边露天煤矿端帮煤炭的高效安全回收有理论指导的作用。

In Ordos Dalad banner Aobaoliang area there exist more than 10 small and medium-sized open pit, including the open- pit of Polly, unreasonable mining order Widespread, no scientific and effective mining on end slope coal, not on the slope safety attention, not to take timely and effective measures to help the pressure causing slope serious security risks. Common package beam area open-pit side slope mining problems and make the appropriate theoretical scheme for efficient and safe recovery of coal to take on the surrounding surface mine end slope theoretical guidance.
