摘要
文章以山西某1000 kV电力工程为例,选取较典型的两处线路杆塔位,根据场地及地形条件分别布置高密度电法和瞬变电磁法测点,实现了对采空区的准确探测和综合解译。同时基于综合物探解译成果及相关规范,对该工程典型塔基位置的压矿稳定性进行了评价。结果表明,综合物探测试结果很好地判断了塔位下方采空区煤层的完整程度,两处塔位采空区顶板及地基处于基本稳定~稳定状态,为该工程杆塔压矿稳定性设计奠定了坚实可靠的数据基础。
Taking a 1000 kV electric power engineering in Shanxi as an example,two typical line tower positions are selected,and the measurement points with high-density electrical method and transient electromagnetic method are arranged according to the site and terrain conditions,so as to realize the accurate detection and comprehensive interpretation of the goaf.At the same time,based on the comprehensive geophysical interpretation results and relevant specifications,the ore pressing stability evaluation of the typical tower foundation position of the engineering are carried out.The results show that the comprehensive geophysical exploration test results have well judged the integrity of the coal seam in the goaf under the tower position,and the roof and foundation of the goaf at the two tower positions are in a basically stable to stable state,which lays a solid and reliable data foundation for the ore pressing stability design of the tower in engineering.
