摘要
地震波在煤岩层面会发生反射。根据这一性质,设计了用不同频率的地震波来探测煤层厚度的方案。通过数值模拟较好地探测出煤层的厚度,从而解决了放顶煤的放顶力度的确定问题,为准确计算回采率和三量管理做出贡献。
Seismic reflection can happen in the coal rock bed. According to the nature,designed a method which is used to detect the thickness of coal seam by using different frequency seismic waves. The thickness of coal seam can be detected well through numerical simulation, and the problems of extent determination were solved in top-coal caving mining. It can make a contribution to the calculation of recovery rate and three variables management.
