摘要
通过对煤矿采空区地震地质条件分析,在野外采集参数,资料处理方法上进行充分试验,获得了采空区范围内高信噪比、高分辨率的地震资料。在时间剖面上准确刻画了采空区边界;采空区下部薄煤层反射波连续性好分辩率高;通过四维地震资料对比,可以观测到采空区内部塌落岩层的压实程度及均匀性;该技术可为煤矿安全生产、预防和治理煤矿塌陷区地质灾害提供地质依据。
The seismo-geologic condition of the gob area of a coal mine is analyzed,many tests are made in order to study the collected parameters and data processing methods,and then the seismic data with high resolution and high signal-noise ratios are obtained.The boundary of the gob area has been lined out correctly on the time sections.The reflex wave of the thin coal seam under the gob area is continuous and has high-resolution.Through contrasting four-dimensional seismic data,the compactness and the uniformity of the interior strata can be descried.This technology can be used to provide geological status for coal mine safe production and for preventing and treating the geological disaster of the subsidence area of coal mines.
