摘要
煤矿的安全生产受到矿区内断层构造的影响,微动探测技术应用于矿山开采运输造成的干扰环境和矿区复杂的场地条件。该文应用基于空间自相关方法的微动探测法,以山西介休鑫峪沟煤矿为例,反演得到观测点地下视S波速度结构,推断地下介质分布信息,研究其对煤矿断层的探测效果。结果显示,此次微动探测工作对矿区内的断层勘探具有较高的分辨率,对断层的空间位置、断距,显著地层分界面有较好的反应。研究结果可为该区域的后续开采提供参考依据。
The safety production of coal mine is affected by the fault structure in the mining area.The microtremor survey technology is applied to the interference environment caused by mining and transportation and the complex site conditions in the mining area.In this paper,the microtremor survey method based on spatial autocorrelation method is applied.Taking Xinyugou coal mine in Jiexiu,Shanxi Province as an example,the apparent S-wave velocity structure of the observation point is inversed,the distribution information of the underground medium is inferred,and the detection effect on the coal mine fault is studied.The results show that the microtremor survey work has a high resolution for fault exploration in the mining area,and has a good response to the spatial position,fault distance and significant stratigraphic interface of the fault.The study can provide reference for the subsequent mining in this area.
