| 摘 要： | 1 INTRODUCTION Water solution mining-based mineral deposit belongs to the ancient landlocked evaporation of salt lake mineral deposits. The salty mineral products of mining area, such as verde salt, rock salt, glauberite, etc., mainly exist in the salty rock segment that is formed by the third sulphate sediment of group of new ditch. This rock segment consists of mudstone, anhydrite-included calcium Glauber’s salt rock, calcium Glauber’s salt rock of mudstone quality, verde salt and roc…

| Abstract: | Based on the hazard development mechanism, a water solution area is closely related to the supporting effect of pressure-bearing water, the relaxing and collapsing effect of orebody interlayer, the collapsing effect of thawless material in orebody, filling effect caused by cubical expansibility of hydrate crystallization and uplifting effect of hard rock layer over cranny belt. The movement and deformation of ground surface caused by underground water solution mining is believed to be much weaker than that caused by well lane mining, which can be predicted by the stochastic medium theory method. On the basis of analysis on the engineering practice of water solution mining, its corresponding parameters can be obtained from the in-site data of the belt water and sand filling mining in engineering analog approach. |
