On the one hand flammable ice or in the vastness of the ocean bottom, or at risk far alpine permafrost zone, the development very difficult.
试验结果证明，复合不耦合装药结构可以降低工作面温度和减小对周围保留冻土爆破振动的损伤。
The test results have proved that the compound non-coupling charging structure can reduce the temperature of the working face and the blasting vibration damage on the reserved frozen soil.
冻土帷幕最大水平位移位置均出现在开挖面以下，一般出现在帷幕全深的0.7-0.8倍深度范围内；
The maximum horizontal displacement occurs below the excavated surface with the depth of 0.7~0.8 times of the pit depth.
