天然碱矿综合钻井水溶开采工艺设计

Comprehensive borehole solution mining design for trona mines

针对土耳其卡赞天然碱矿的地质特征和生产现状,为降低采矿成本,充分利用矿产资源,解决当前开采中存在的工艺问题,提出了一种“综合钻井水溶开采法”。通过对各个布井参数的确定,根据一定布井原则,对整个矿区进行了钻井开采工艺设计。该方法采用了水平井、分支井、对井压裂、单井吞吐等多种开采形式和井组类型。

This paper presents a comprehensive borehole solution mining methodology in light of the geology and production at the Turkish Kazan trona mine in order to reduce mining costs,make full use of mineral resources,and solve some problems with the existing mining process.A borehole solution mining process has been designed by determining the various parameters and principle of the well layout.The process combines a variety of mining forms and well group types,such as horizontal well,branch wells,fractured wells,close-loop circulation single well and so on.
