超千米水文补勘钻孔设计优化及安全质量控制

Above one kilometer depth hydrological supplementary exploration drilling design optimization and safety and quality control

兖州矿区各矿井面临采区接续紧张和向深部开拓问题,原勘探资料不能满足需要。深部地质条件复杂、埋藏深度大,造孔深度超千米以上,施工技术难度大,需对设计进行合理优化,加强施工过程中的安全和质量控制,确保达到勘探目的。

The mines of Yanzhou mining area have the problems of lack of mining area and exploration to the deep development, in addition, the original exploration data can not meet the needs. The complex geological condition in deep area, deep buried depth, above one kilometer depth pore and big con- struetion difficulty have caused the device to be designed reasonably, at the same time, the safety and quality control in the process of the construction should be strengthened to ensure the exploration target.
