崩落法纵向分区开采突破了以往纵向分区开采中下部分区不能使用崩落法的限制,克服了矿体条件对产能的制约,是提高矿山生产能力的有效措施。在阐述崩落法纵向分区开采现状的基础上,明确了该方案的相关关键问题,从开采方案的适应性、岩体可冒性、上下分区间生产协调、纵向分区开采冒落危害防治几个方面分析该方案要点,提出了崩落法纵向分区开采理想的矿床条件、岩体冒落临界值的参数控制、合理的临时矿柱留设与保持,以及根据具体冒落危害形式采取有针对性的防治措施,并指出了崩落法纵向分区开采今后的研究方向。
Longitudinal subsidence mining subsidence broke the vertical division of mining in the lower part of the area can not use the caving method restrictions to overcome the constraints of ore production capacity constraints is an effective measure to improve mine production capacity. On the basis of elaborating the status quo of vertical subsidence mining, the key issues related to the scheme are clarified. From aspects of adaptability of mining plans, feasibility of rock mass production, production coordination between upper and lower sub-zones, The key points of this scheme are analyzed, the ideal deposit conditions for longitudinal subsidence mining of caving method, the parameter control of the critical value of caving of rock mass, the establishment and maintenance of reasonable temporary pillars are put forward, and the targeted prevention and treatment Measures and pointed out the future research direction of vertical subsidence mining method.
