【摘要】 对当前微地震的主要定位方法包括P波定位法、地震波射线法、P波射线传播方向交汇点法等推导的定位公式进行了对比分析,总结了各自优缺点及适用条件。同时在实验室利用预制的混凝土模型,模拟矿山监测环境,采用P波定位法对其模拟定位,定位结果与实际情况进行比较,破裂位置基本吻合(定位精度±1m),表明微地震技术能满足采矿工程中的应用条件。更多还原

【Abstract】 The currently used main microseismic location methods and their location formulae are contrasted,including P-wave location method,seismic wave ray method,P-wave ray propagation direction intersecting point method.Their advantages and disadvantages and applicable conditions are summed up.Meanwhile a prefabricated concrete model is used to simulate mine monitor environment.P-wave location method is adopted to conduct its simulation location.The location results were compared with practical situation.The location precision is ±1m and is very close to the real fractured place.It indicates that the microseismic technology can be applied to mining engineering.更多还原
