| 摘 要： | 用粉煤灰水泥砂浆灌注法对榆林热电公司拟建的1 250 m2冷却塔煤矿采空区地基进行了处理,通过对处理后的采空区进行钻探抽芯和面波测试,结果表明:钻探抽芯试块强度满足设计要求,面波检测的原采空区区域已被浆液充满,形成固结体,固结体波速均高于原岩,达到了处理的目的.

| Abstract: | The ground of colliery gob of 1 250 m2 cooling tower of Yu Lin thermoelectricity Co.is treated with perfusion method of coal powder and sand-cement slurry.The result indicates that the intensity of specimen meets the need of engineering design,and the gob of side-wave testing is permeated with the slurry.Also,it becomes solidified body.The wave velocity of solidified body is higher than the original rock.Thus,the aim is reached through sampling and side-wave testing. |
