全面法矿柱回采地压显现监测与安全保障措施

Thoughts on the combing of potential safety hazards in room and pillar mining method and its countermeasures

全面法矿柱开采应力分布极为复杂,单纯依靠理论计算和数值模拟手段并不能完全掌握其地压显现规律。本文就全面法矿柱回采制定了监测方案并就监测结果进行了分析,最后制定了安全保障措施,以期为今后国内类似开采技术条件的矿山开采提供一定的参考依据。

The stress distribution of pillar recovery in the room and pillar mining method is extremely complicated.It is impossible to fully obtain the law of ground pressure manifestation by relying solely on theoretical calculations and numerical simulations.In this paper,a monitoring plan is developed for the pillar recovery,and the monitoring results are analyzed.Finally,safety and security measures are formulated to provide a reference for mining in the future with similar mining technical conditions.
