近年来,三维地震技术在煤矿中得到了很广泛的应用,在矿井和采区设计优化、避免和减少地质风险、优选采煤方法、提高资源回收率、降低万吨掘进率等方面起到了重大作用,但在实际应用中,却暴露了许多问题,比如利用率低、无法实时获得巷道地震剖面、无法圈定火成岩侵蚀范围等等一系列问题,引入三维数据管理系统后,它能使地震资料随煤矿生产进行全程动态解释,提高三维地震成果利用水平,以便更好指导煤矿生产,为煤矿节约的成本与时间,本文就以祁东煤矿三采区陷落柱验证孔的设计与6137工作面煤层变薄带范围的圈定为例说明其在实际中的应用。
In recent years, 3D seismic technology has been widely used in coal mines and has played a significant role in the design and optimization of mines and mining areas, avoiding and reducing geological risks, optimizing coal mining methods, increasing resource recovery, and reducing drilling lead per 10,000 tons However, in practical applications, many problems have been exposed, such as the low utilization rate, the inaccessibility of real-time laneway seismic profiles, the inability to delineate the scope of igneous rock erosion and so on. After introducing the 3D data management system, it can make the seismic data Coal production to explain the whole dynamic process to improve the level of utilization of three-dimensional seismic results in order to better guide the coal production, cost savings and time for the coal mine, the Qidong coal mine in the three subsidence column verification hole design and 6137 coal face change The band definition of the strip as an example to illustrate its practical application.
