摘要/Abstract

摘要： 来龙矿区方解石矿山采空区群体积已经达到了350万m3，矿体低价值的属性造成了采空区治理安全与经济的矛盾。为了有效地治理采空区，首先对350万m3的采空区进行了三维测量，建立了三维模型，然后对矿区的工程地质进行了调查，对采空区稳定性进行了评估，开发了采空区围岩稳定性连续监测系统，在矿区采空区群治理中得到了很好的应用。

Abstract: The goaf volume in calcite mine of Lailong mining area has reached 3,500,000 m3，and the low value of orebody results in contradiction between the management and security of goaf and the economy.In order to effectively control the mined-out area，3D model for 3,500,000 m3 of goaf was established based on 3D measurement，and then the engineering geology of the mining area was investigated.Based on evaluation on the stability of mined-out area，the continuous monitoring system for surrounding rock's stability in goaf was developed and has been widely applied in treatment of goaf.

Key words: Low-value ore-body, Goaf sealing, Stability monitoring
