【摘要】 应用三维地震勘查方法进行煤矿塌陷区调查,既能够准确圈定采空区范围,又能够很好地解释中、浅层塌陷区分布。三维地震能够克服地质雷达、电法、地震横波等传统勘查方法勘探深度浅(一般为30 m,最多不超过50 m)的缺点,其成果对煤层在30 m以下老矿区综合治理、合理开发利用,提供准确地质资料。更多还原

【Abstract】 The investigation of the coal mine subsidence area by 3-D seismic prospecting method can accurately delimit gob area as well as can explain the distribution of intermediate,hallow subsidence areas,The 3-D seismic prospecting method can overcome the weakness that prospecting depth is relative shallow by traditional prospecting method-geologic radar,electrical prospecting,transverse seismic wave and so on,It can accurately provide geologic result for developing and using the old mining area that is under 30 m.更多还原
