摘要
为解决大宝山矿668-1采空区给生产带来的安全隐患,在对该采空区的基本特征、地质条件、顶板保安层稳定性等情况进行调研的基础上,选择强制崩落方案进行处理。经现场实测,该次采空区处理达到了预期的效果:采空区除边缘部分外基本都已坍塌;未影响到附近的平硐及选矿厂等地表工业建筑的正常运行;采用爆破处理经济效益显著,处理周期短。
To eliminate the potential safety hazard at 668--1 goal in Dabaoshan open-pit, forced caving method was se leered based on large amounts of investigation such as basic characteristics, geological conditions, and the stability of roof security layer. Practical results proved that this goaf dis- posal achieved desired goal in a short treatment period. The goaf area collapsed except little edge part, having little im pact on nearby industrial buildings, and gained significant e conomic benefit.
