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.
The ground of colliery gob of 1 250 m^2 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 desigin,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 samphng and side-wave testing.
