【摘要】：煤矿开采后形成的采空积水区是影响矿井生产和建设的重大安全隐患之一。胜利矿井田范围内分布着早期开采的47个大小煤矿,特别是其中45个小煤窑开采时间长短和规模不一,开采随意性强,越层、越界、乱采现象明显,采掘后形成大量无记载、无规则的采空积水区。查清采空积水区位置、范围等赋存情况,对采取积极措施防止采空区积水引发的水灾事故发生,保证人身和财产安全和实现矿井安全高效生产具有重要的意义。为了探测2#层采空积水情况,对勘探区范围,测点和测线间距进行了设计。通过试验确定了适合本次勘探任务的主要设备仪器测试参数,并在完成测试任务后对测试结果质量进行了评价分析。结合采空区地球物理和探测结果特征,提出了采空积水区的判定方法。然后对2#层的采空积水区范围进行了分析,共推断出6个采空积水区。借助2#层的探测结果尝试对6#层的采空积水区进行了分析,共推断出3处采空积水区。最后利用推断形成采空区的开采煤矿的方法,对各采空积水区进行了进一步的验证。在介绍井下瞬变电磁法探测原理的基础上,设计了在三条井巷中布置12个测站、共计24个测面的探测方案。根据视电阻率在剖面图上的分布规律,提出了低阻异常区的分析判定方法及流程,并依其对各测面的测试结果进行了分析。共发现2#层采空积水区三处,6#层一处。通过与地面物探结果对比分析,两个测试结果对比分析可知,吻合度较高,说明测试结果具有较高的可靠性。
[Abstract]:The goaf is one of the major safety problems affecting mine production and construction. Within the scope of Shengli mine field, there are 47 large and small coal mines that were mined in the early stage, especially 45 small coal kilns, in which the mining time and scale are different, the mining is arbitrary, the phenomenon of overstepping the boundary and the random mining is obvious, and a large number of unrecorded mining is formed after mining. An irregular emptying area. It is of great significance to find out the location and scope of the goaf, to take active measures to prevent the flood accident caused by the water accumulation in the goaf, to ensure the safety of the person and property and to realize the safe and efficient production in the mine. In order to detect the emptying of strata in 2#, the range of exploration area, the measuring points and the distance between surveying lines are designed. The test parameters of the main equipment and instruments suitable for this exploration mission are determined through the test, and the quality of the test results is evaluated and analyzed after the completion of the test task. Based on the geophysical and detection characteristics of goaf, a method to determine the goaf is proposed. Based on the analysis of the area of water accumulation, six areas are inferred. With the help of the results of the exploration of the 6 # bed, the paper analyzes the hydrologging area of the 6 # bed, and inferred three areas of water accumulated in the caved out. Finally, the method of inferring the mining coal mine in goaf is used to further verify the water accumulation area. On the basis of introducing the detection principle of downhole transient electromagnetic method, the detection scheme of 12 stations in 3 wells and alleys, with a total of 24 survey planes, is designed. According to the distribution law of apparent resistivity on the profile, the method and procedure of analyzing and judging the low resistivity anomaly area are put forward, and the test results of each measuring plane are analyzed according to the method. A total of three empty water mining zone and one 6 # layer were found. By comparing and analyzing the results of geophysical exploration on the ground, the comparison and analysis of the two test results show that the degree of coincidence is high, which indicates that the test results have high reliability.
