摘　　要：某些矿种因为价值较低,一般采用房柱法开采缓倾斜薄的矿体。又由于其自身矿岩强度可能较低,带有明显的软岩特征,此时,矿房稳定性对于矿山安全生产具有非常重要的意义。考虑到矿房稳定性受矿房暴露面积、矿房顶板矿岩体质量及矿房所受地应力等多种因素影响,采用物元分析法对矿房稳定性进行了分析:先确定矿房稳定性影响因素的分级标准,根据各待分析矿房的稳定性影响因素指标实际值,计算其对于各影响因素的各经典域和节域的距离,并根据层次分析法确定各影响因素的权重,进而计算矿房各稳定性等级的综合关联度,进而根据最大隶属度原则对矿房稳定性进行判定。实例证明:物元分析法可以对矿房稳定性进行科学分析和准确评价,进而可为矿房有针对性地采取维稳措施提供参考与依据,实现矿房经济高效维稳。Due to the low value of certain minerals,the room pillar method is generally used to mine gently inclined and thin ore bodies.Due to its low rock strength and obvious soft rock characteristics,the stability of the mining room is of great significance for the safe production of the mine.Considering that the stability of the mining room is influenced by various factors such as the exposed area of the mining room,the quality of the rock mass on the roof of the mining room,and the ground stress on the mining room,the matter-element analysis method was used to analyze the stability of the mining room.Firstly,the grading standards for the factors affecting the stability of the mining room were determined,and based on the actual values of the stability influencing factor indicators of each mining room to be analyzed,the distances between the classical domains and nodal domains of each influencing factor were calculated,According to the Analytic Hierarchy Process,the weights of each influencing factor are determined,and the comprehensive correlation degree of each stability level of the mining room is calculated.Then,the stability of the mining room is judged based on the principle of maximum membership degree.Example proof:The matter-element analysis method can scientifically analyze and accurately evaluate the stability of mining rooms,and can provide reference and basis for targeted stability measures taken by mining rooms,achieving efficient economic stability maintenance of mining rooms.
