摘要
为了提升煤矿采空区勘察及其稳定性评价效果,应用微动探测技术,设计一种煤矿采空区勘察及其稳定性评价方法。利用GT-MST微动测试仪勘察煤矿采空区,该仪器的配置具体包括GT-MST基站、检波器、天线等。考虑到勘查实施过程、人员调配、仪器运输等问题,勘查前需要设计勘查方案,并以勘察方案为基础设计微动台阵。在此基础上,构建煤矿采空区稳定性评价体系,无量纲化处理评价指标数据。选择某煤矿采空区作为实验采空区,利用该方法对该区实施勘察与稳定性评价,以期为工程的实施提供基础施工、设计数据。测试结果表明,该方法的勘察误差较低、评价准确率较高,具有一定实用性。
In order to improve the effect of coal mine goaf survey and stability evaluation,a method of coal mine goaf survey and stability evaluation is designed by using micro motion detection technology.GT-MST micro motion tester is used to survey the goaf of coal mine.The configuration of the instrument includes GT-MST base station,geophone,antenna,etc.Considering the implementation process of exploration,personnel allocation,instrument transportation and other problems,it is necessary to design the exploration scheme before exploration,and design the micro motion array based on the exploration scheme.On this basis,the stability evaluation system of coal mine goaf is constructed,and the evaluation index data are processed dimensionless.The goaf of a coal mine is selected as the experimental goaf,and the method is used to investigate and evaluate the stability of the area,in order to provide basic construction and design data for the implementation of the project.The test results show that this method has low survey error,high evaluation accuracy and certain practicability.
