| 摘 要： | 针对淮南煤田急倾斜含煤地层常规勘探手段受限问题, 通过对淮南煤田罗园井田控煤构造及资源赋存状态分析, 结合规范要求, 采用定向造斜钻孔与铅直钻孔相结合的钻探工程布置方式, 先实施铅直钻孔, 再实施定向造斜钻孔。实施效果表明, 既降低了勘探成本, 又提高了勘探工作效率, 技术和经济效益较为明显。

| Abstract: | Through the analysis of tectonic styles controlling the coal seam distribution in LuoYuan Mine Field, and in the background of high precision and fast exploration, and in preconditions that the function of conventional seismic exploration mean was restricted, combined with standard requirement, we chose more objective and reasonable exploration technique suitable for the exploration of this particular form of resource storage in this coalfield. And we confirmed the drilling engineering layout mode, which was combined with directional inclined borehole and vertical borehole, and put it into practice. It reduced the exploration cost, improved exploration work efficiency, and obtained more obvious technical and economic benefits. |
