平朔露天矿生产地质勘探钻孔布设方法

Borehole layout for production geological exploration in Pingshuo open-pit mine

露天煤矿生产地质勘探贯穿于煤矿生产全过程,为了全面获取地质信息,保障合理配采,指导生产接续。平朔公司依照相关规程规范及多年的生产地质勘探经验,提出了生产地质勘探应遵循"补充近三年、适度超前、一孔多用"的设计原则及等高距、构造、煤质、长远规划等钻孔控制的布设方法。结果表明:利用该方法可为露天煤矿提供更为详细准确可靠的地质资料。

The geological exploration of open-pit coal mine runs through the whole process of coal mine production, in order to obtain comprehensive geological information, ensure reasonable allocation of production, and guide the continuation of production.Pingshuo company according to the relevant specifications and years of production geological exploration experience,the design principles of "supplement nearly three years, moderate advance, multi-purpose drilling" and the layout methods of drilling control such as contour interval, structure, coal quality and long-term planning are put forward for production geological exploration.The results show that this method can provide more detailed, accurate and reliable geological data for open-pit coal mine.
