The invention provides a method for analyzing a main controlling factor of a deep mining surrounding rock ground pressure disaster precursor, and relates to the technical field of ground pressure disaster prediction and control. According to the method, ground pressure disaster prediction before and after mining on a mining surrounding rock is conducted by using rock stratum stress, compressive strength, charge and energy as monitoring indexes, and the ground pressure disaster prediction accuracy and the prediction precision can be improved; according to the method, monitoring is conducted byadopting the rock stratum stress and the compressive strength before mining surrounding rock mining, the danger level of the mining surrounding rock is judged according to the monitored rock stratum stress and the compressive strength, and whether mining is conducted or not is judged; and the charge and acoustic emission events are monitored during a mining process of the mining surrounding rock or the danger level of the mining surrounding rock is at the non-mining level, a real-time danger degree of the mining surrounding rock is judged according to the monitored charge and acoustic emissionevents, and early warning is carried out when the early warning condition is met. The technical scheme provided is suitable for a prediction process of mining surrounding rock ground pressure disasters.
Description
【Technical field】 [0001] The invention relates to the technical field of prediction and prevention of ground pressure disasters, in particular to a method for analyzing main controlling factors of precursors of rock pressure disasters in deep mining surrounding rocks. 【Background technique】 [0002] Ground pressure disasters in deep mining are frequent, and certain characteristics will appear before they occur. Grasping these characteristics can effectively predict and prevent them. However, the current analysis of the characteristic information of deep rock pressure disaster precursors is insufficient, and the main controlling factor analysis method has not been formed, and the main controlling factors of disaster precursors have not been found. The main control factor is not clear. [0003] Therefore, it is necessary to study a method for analyzing the main controlling factors of the precursors of rock pressure disasters in deep mining to deal with the deficiencies of the...
