巷道

The results show that the key rock-beam situated at the outside of the structure acts as a framework, shielding and interdicting the transference of stress. This is true not only in the vertical but also to a great extent in the horizontal direction as well.

结果表明：外层关键岩梁结构在巷道变形过程中起到骨架作用，屏蔽和阻断应力的传递，不但使得巷道跨度范围内垂向应力的传递发生阻断，上部岩层载荷不能向关键岩梁下位岩层传递，而且承担了开挖引起的应力重分布的大部分水平应力。

Based on the knowledge and results gained from detail researches, select some a roadway as trial area to study further and validate the structural rheology and to search the sound countermeasure. The trial roadway, 50 m long, is portended that very large deformation and serious damage will happen, so its stability is very poor and its support very difficult.

Following the method commonly used in the detecting of geological structure and water gush in coal mines, we carried out a test exploration of audio-frequency electric perspective in No.

常规电法仪器测量精度低，抗干扰能力差，无法抵抗巷道铁轨以及运行矿车的强大直流电干扰，因而不能胜任金属矿的井下巷道探测任务。

Both theory and practice indicate that the stability of rock can be achieved through fully exerting the mutual action between the bolt with wire mesh and the surrounding rock.

理论和实践表明，深部全煤巷道通过强化支护和适度让压，充分发挥锚网－围岩整体力学效应，可以达到巷道稳定的目的。

The result of monitoring consequence of bottom tunnel in period of excavating and withdrawal reveals that the way of suitably increasing length and diameter of the anchor,and building the bottom anchor can effective.

通过对底板煤巷掘进期与回采期巷道变形现场监测表明：适当加大锚杆长度与直径，并在底板煤巷底帮增加布设底锚能够有效降低回采巷道变形量。

In the seismic records of plane wave source the cavity underneath the roadway shows as a obviously unusual "candied fruit".

利用平面波震源在巷道内激发产生的波场中，巷道下方的空洞在平面波震源激发的地震记录上，其多次反射绕射波互相叠合在一起，表现为&糖葫芦&状的明显异常特征。

The common embedded beam method can' t be used to fix the transbeam of supporting roller in the erection of the aerial miner' s truck in the coal tunnel of Dongqu Co al Mine.

东曲矿全煤巷道中安装架空人车无法采用常规的预埋梁法固定托轮横梁，根据锚杆工作原理，将树脂锚杆应用到架空人车的托轮横梁固定安装中，较好地解决了架空人车在全煤巷道中的安装难题，达到了预期的安装效果。

The results show that the study on transimittivity can be done using the points along the circle arc centered at the roadway or the boring core, the transimittivity at the joints along the right angle ray can be studied using one single point behind the joint, and the studies on transimittivity can be done on any reasonable radius value of the roadway or boring core in a typical rock.

分析结果表明：单节理后各节点透射率的研究，可以通过单节理后某一以巷道或钻孔中心为中心的圆弧上各节点的透射率来展开；射线角为90°的射线上节理后各节点透射率的研究，可以通过节理后某一节点的透射率来展开；单节理的透射率的研究可以在一个固定半径值的巷道或钻孔的模型上用一种典型的岩石进行。

Derformation and convergence survey were made on the drift of Qiaohou Salt Mine withthree techniques.

叙述了对乔后盐矿井下巷道进行变形和收敛观测的结果，分析了观测数据，主要结论：自60年代以来该矿岩盐巷道的收敛速度已明显加快，垂直方向的日平均收敛量已由60年代初期的约0。

Underground whole-space transient electromagnetic method was tested at the driving face of a drift in a coal mine for detecting water-bearing zones ahead of tunneling.

根据初探结果，采用不共面同轴偶极观测方式时，UWTEM在巷道掘进头前方的有效探测范围约为70m，巷道每掘进50m进行一次跟踪探测。

I am sure after a few weeks of adaptation and familiarization I will have no difficulty in functioning on a daily basis in an English speaking society or in participating fully in graduate studies.

在大学的三年的学习生活不仅给予我自身的充实，更重要的是磨练和培养了我较强的自觉能力和严谨，踏实的作风以及不怕困难的精神，对未来充满了信心！
