Case study on the effects of seismic exploration beneath the goafs of different ages

  • 摘要: 随着煤炭资源的持续开发,部分煤矿上组煤已经开采殆尽,亟需开展下组煤的探测工作。受上组煤采空影响,下组煤地震波能量吸收和散射衰减严重,资料信噪比低,三维地震对采空区下组煤的探测尚属于探索阶段。以冀中能源东庞矿采空区下组煤三维地震勘探项目为例,采用“两宽一高”采集、高精度资料处理和属性体解释等技术,对不同年限采空区下组煤的探测效果进行了对比分析。结果表明:采用“两宽一高”采集技术能够获取采空区下组煤的地震信息;振幅补偿、地震拓频技术使得9号煤反射波波组丰富、连续性好;采空区年限大于10年时,破碎岩层压实,相对稳定,下组煤反射波利于追踪,而小于10年时,岩层破碎未压实,导致下组煤反射波能量弱、杂乱无章。这一认识对于类似煤矿采空区下组煤探测具有一定的指导意义。
