Matter-element Analysis Method for Stability Analysis of Mine Rooms
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.
