1) thick bed rock
厚基岩
1.
Recently, with the extension of the mining face, the mining height and the height of the bed rock of the overburden in Shengdong coal area, the study of the overburden movement and mining pressure behavior of shallow coal seam with thick bed rock becomes the new problem.
近几年随着神东矿区工作面的加长、采高的逐渐增大、上覆岩层基岩厚度增大,厚基岩浅埋煤层覆岩移动和矿压显现规律研究无疑成为了新问题。
2) bedrock pillar thickness
基岩柱厚度
1.
A borehole water injection method was applied to probe the mining failure height of the strata after the coal mining operation of the fully mechanized longwall caving mining face in Yangcun Mine and also to probe the bedrock pillar thickness in the direct roof No.
通过采用钻孔注(放)水法探测了杨村煤矿综放面采后覆岩采动破坏高度;同时,探明了305工作面浅部顶板基岩柱厚度;采用无线电波坑道透视方法,查明了工作面内的隐伏小断层及其延展情况。
3) utmost bedrock ply
极限基岩厚度
1.
Through the way of numerical simulation and locale measurement,we found the safety utmost bedrock ply at the condition of thin bedrock and thick coal seam in Sima Coal Mine.
通过数值模拟和现场实测的方法,研究了司马矿薄基岩厚煤层开采条件下,保证安全开采的极限基岩厚度。
4) Thick bedrock thin topsoil
厚表土薄基岩
5) depth of soil overlying bed
基岩上复土层厚度
6) super-thick magmatic stratum
巨厚岩浆岩
1.
Based on mining condition which is covered by super-thick magmatic stratum,failure conditions and failure modes of magmatic stratum are studied by means of analytical solution—theory of thick plate rested on elastic foundation when mining is carried out in different stages.
以巨厚岩浆岩下采矿工程为背景,运用弹性基础厚板理论研究巨厚岩浆岩下煤层不同开采阶段对上覆岩层的影响以及岩浆岩变形规律与破坏模式。

天柱山天柱峰
天柱峰又称为皖伯尖，万山尖。《道书》称为司命真人发祥所都，海拔1488.4米，孤立晴宵，顶天立地，石骨嶙峋，峭立如柱。五指、莲花、天池、含珠、飞来、月华诸峰拱卫左右，奇松、怪石、云海、佛光、各领风骚。李白《江上望皖公山》诗云：“奇峰出奇云，秀水含秀气。”白居易《题天柱峰》诗云：“天柱一峰擎日月，洞门千仞锁云雷。”
