摘要
老空区探测是一个亟待解决的技术难题。自2001年,美国从地面、井下、孔间以及孔—地等立体空间,建立了巷道实体测试模型、巷道系统测试模型和废弃矿井验证模型,借助于14个示范工程,系统开展了老空区探测物探方法的测试与实物验证,对不同探测技术的实效性进行了初步的评价。分析认为:在老空区探测中,美国采用的实物模型测试探测方法有效性的做法值得我们学习和借鉴。
It is an urgent technical problem to be solved for gob detection. After 2001,the real roadway model,roadway system test model,and abandoned coal mine verification model were established for testing various detection methods used in gob,which could be done from surface,underground,cross hole,and surface to subway. On the basis of 14 demonstration projects,the test and actual verification on geophysical methods used in gob detection were conducted,and the effectiveness was evaluated. The results showed that the actual model used for geophysical method test in USA is worthy of our learning.
