【摘要】 对河南永城李大庄煤矿首采区进行了三维地震勘探,该技术在解决小于5m的高精度断层上起到了很好的地质效果。通过三维地震勘探可以弥补单凭钻孔无法准确确定构造组合及延展长度等问题。对于构造相对复杂的区域采用三维地震勘探的方法能够起到高精度、低成本、效率快的勘探效果。更多还原

【Abstract】 Yongcheng Lidazhuang Henan mine first mining area conducted three-dimensional seismic exploration,the technology played a very good geological effects for less than 5m high accuracy in solving faults.Three-dimensional seismic exploration drilling alone can not accurately determine the offset portfolio and extend the length of the structure and other issues.Relatively complex area for constructing three-dimensional seismic exploration method can play a high-precision,low-cost,fast efficient exploration results.更多还原
