昆明盐矿溶腔稳定性及继续上溶开采分析

Analysis on Dissolved Cavity Stability and Upper Boundary Exploitation of Kunming Salt Mine

昆明盐矿首采区四口采卤井经过多年的开采,卤井溶腔顶界已达原开采设计方案设计开采的最上界,为缓解资源压力,昆明盐矿依据实际情况,认为继续上溶开采是目前矿山提高综合回采率的主要途径。

After the long-term exploitation of four brine wells in the First Exploitation District Kunming Salt Mine, the top boundary of brine well dissolved cavity has reached the highest boundary of exploitation in the original designing scheme. In order to relieve the resources pressure, Kunming Salt Mine basing on the actual situation, considers that dissolved exploit the upper boundary is the main way to increase the comprehensive recovery percentage of mines.
