基于高分辨率地震反射波法的公路下伏采空区勘查

【摘要】 采用高分辨率地震反射波法对十大高速公路窑沟采空区进行勘查,在地震勘查测线总计解释煤层采空段7处。勘查结果表明,在采空区调查中采用高分辨率地震散射波法地震勘查的技术是可行且有效的。在地震勘查数据采集中,选择了S―Land全数字化地震数据采集系统和机械冲击震源的实际应用效果表明,在黄土塬沟壑地区采用非爆炸震源进行地震勘查是可行的,这为该区采用地震勘查进行采空区调查积累了经验。更多还原

【Abstract】 Using high resolution seismic reflection wave method to explore Shiqigou- Dafanpu Highway kiln ditch mined-out area,there are 7 worked- out sections of the seismic exploration line. Exploration results show that in the investigation of mined- out area adopts the method of high resolution seismic scattering wave seismic exploration technique is feasible and effective. In seismic exploration data acquisition,the application effect of S- Land fully digital seismic data acquisition system and mechanical shock focus show that the using un- explode focus conduct earthquake exploration in Huangtuyuan gully area is feasible,which accumulate experience for gob investigation with earthquake exploration.更多还原
