中文摘要:
      为了有效地预警程潮铁矿采场地压显现的易发性状况,通过现场调研选取埋深、抗压强度和顶板管理等8种影响因素作为评价指标,利用变异系数法赋予各项评价指标的权重,基于密切值法理论建立采场地压显现预警模型。将此模型应用于程潮铁矿的油库和5-1工作面,通过分析密切值的大小预测程潮铁矿的油库和5-1工作面的易发性状况。结果表明:油库有低易发的危险;5-1工作面有中易发的危险;该模型预警结果与实际状况相吻合。可见该方法有效可行,能够为矿山采场地压显现的预警提供有益的指导。
英文摘要:
      In order to effectively early warning of the susceptibility of the pressure appearance of the quarry, through the field investigation, 8 kinds of influencing factors, such as buried depth, compressive strength and roof management, are selected as the evaluation indexes, the weight of each evaluation index is given by using the coefficient of variation method, and the early warning model of the pressure display of the mining site is established based on the This model is applied to the oil depot and 5-1 working face of Cheng Chao Iron mine, and the susceptibility of oil depot and 5-1 face in the process of tidal iron mine is predicted by analyzing the size of the close value. The results show that the oil depot has the risk of low susceptibility, 5-1 working face has the danger of being prone to hair, and the early warning results of the model are consistent with the actual situation. It can be seen that this method is effective and feasible, and can provide useful guidance for the early warning of the pressure appearance of mine mining site.
