Based on testing data in worksite and engineering practice, the strata damage movement characteristics, rock properties of weathered zone and qualitative and quantitative analysis of the mechanism of coal layer safety extraction in efflorescent oxygenized belts were discussed
摘要根據現場觀測和工程實踐，論述了風氧化帶內煤層開采時，覆巖破壞移動特徵，風化帶巖石屬性和風氧化帶內煤層安全開采機理的定性、定量分析。 -
The ground base of the newly added chute in 4 tailings reservoir at dexing copper mine is characterised by thick weathered layer, loose structure, fractured zone and landslip mass accumulation. as a result, the ground has a great subsidence and inefficient carrying capacity. in view of this, the grouting technology was adopted to reinforce the chute ground base. the on - site testing shows that the subsidence of the chute has been efficiently controlled and the carrying capacity of the ground base improved so that the stability requirement has been met
潘洛鐵礦主要使用的采礦方法是淺眼落礦的全面法和留礦全面法. 23礦體160m以上礦段上部為氧化礦和風化巖層，形成擠壓爆破和鬆散巖石覆蓋下的放礦條件.介紹了無底柱分段崩落法在該礦體開采中的應用.實際使用獲得的各項技術經濟指標還比較理想 -
The landslide feature of the expansive soil is analyzed. the stability of the expansive soil slope is largely dependent on the weal link. the slope stability analysis of the expansive soil should consider the weathering, so all the analysis should be classified to two different types : weathered layer and non - weathered layer
對膨脹土路塹邊坡滑坡特點進行了分析，指出膨脹土邊坡主要受軟弱結構面控制，提出了膨脹土邊坡穩定分析應分為風化層和深層未風化層的方法，並建議了不同部位土的抗剪強度指標取值方法。 -
Such low velocities are usually seen only near the surface in a zone called the weathered layer or the low-velocity layer.
