- When long wall mining to the dip in fully-mechanized coal winning working face is inclined area,we may can't use existing drift draw off water. 当倾斜长壁开采的综放工作面初采范围处于向斜构造区,造成初采放水无法利用已有巷道形成自流放水,必须考虑动力排水或其他的放水方式。
- This enabled them to run transport cars right up to the work face. 这使他们能把运煤车一直开到工作面。
- Stripper face must extend 1/8” below working face of punch. 脱料板下表面至少比冲子工作面高出1/8”。
- Again, according to analyze wall rock change along with working face advancing under caving, the paper gains three different phases of wall rock transmogrification. 再次，分析了采动影响下沿空巷道随着工作面的推进围岩变化情况，得出了围岩变形的三个不同阶段；
- Therefore, the risk of fault rock burst when working face advances from the footwall to the fault itself is higher than that from the hanging wall to the fault itself. 通过对比分析，可确定当工作面从正断层下盘向断层推进时冲击矿压的危险性远高于工作面从上盘向断层推进时的危险性。
- The results show that the stability of roof becomes poor with reduction of distance away from the fault whether the working face is mined in the footwall or hanging wall of fault. 结果表明：无论工作面是由断层下盘向断层推进，还是由断层上盘向断层推进，随着工作面距断层面距离的缩小，顶板稳定性变差。
- All coal was moved from the work face by electrically-driven conveyors. 所有的煤都用电动传送带从工作面运出来。
- I work with the contrary and complementary. The concept of Yin-Yang. “Water” the wall work is executed by my habitual way of working and understanding form and space. 我的作品是将对立和统一结合在一起,也就是所谓的阴阳。墙上作品“水”的构思来源于我工作的习惯方式以及我对空间和外形的理解
- And the properties and amplitude of stress of rock mass in the back of shaft wall at the bottom are related with l ayout of working face, mining sequence, and distance of the working face to shaf t. 观测结果表明：井筒上部壁后岩体在铅垂方向上受张应力影响，而井筒底部壁后岩体应力的大小和性质与工作面的布置方式、开采顺序以及井筒与工作面的相对位置有关。
