工业广场下伏采空区二维地震勘探技术

2-D Earthquake Surveying Technique Used in Gob Exploration for Industrial Square

为查清四老沟矿南羊路工业广场下伏采空区分布,采用二维地震技术对采空区进行勘探。对物探成果进行验证,钻探结果表明物探技术得到的采空区范围准确性高。结合物探技术和钻探验证结果,划定了工业广场下伏采空区综合边界。

In order to get the distribution of the gob below the industry square, the 2-D earthquake surveying technique was used for the gob exploration. And the drilling results of the gob checking drill hole indicate that 2-D earthquake surveying method get a good results in the gob exploration. Finally,the gob area distribution was gained by combining the both outcome of 2-D earthquake surveying method and the drilling results.
