摘要:
无线电波透视技术在煤矿工作面内部隐伏构造的探查方面已有很多的成功实例,目前该方法对陷落柱探查的分辨率和局限性的研究比较少见.为说明该方法对陷落柱探测的可靠性和局限性,从数值模拟和实际透视实例两方面进行讨论.采用数值模拟办法模拟工作面陷落柱响应并对模拟数据进行反演,无线电波透视方法对于孤立的单个或多个陷落柱都有较高的区分度,反演位置与实际情况吻合;对天地王坡煤矿的坑透数据进行处理,圈定了陷落柱的范围,并经工作面回采证实.该工程实例证明了数值模拟的结论:对于横向位置差别不大的陷落柱,无线电波透视分辨能力下降,施工方法限制了分辨能力的提高.
Abstract:
There are a lot of successful examples in coal mining working face internal probe of concealed structure for Radio wave perspective technique,but less research on the resolution and limitation of the method for the collapsing column probe was done.In order to illustrate the reliability and limitation of the method detecting the collapse column,numerical simulation and practical perspective instances are discussed from two aspects,numerical simulation method are adopted to simulate the collapse response in working face and the forward date was carried out on the inversion,The radio wave perspective method for isolation of single or multiple collapse column has a high degree of differentiation,the inversion position matches the reality highly,actual engineering example proved that the conclusion of numerical simulation,for collapse columns which transverse position differ little,the distinguish ability decline,resolution enhancement is limited by the construction method.
