Prevention and control of deep dynamic disasters and resources green exploitation in Pingdingshan Mining Area

The Pingdingshan mining area mined by China Pingmei Shenma Group is a typical example of deep mining. After 70 years of development, the group always insists on leading production with scientific and technological strength, ensuring safety with technical equipment, deepening its understanding of gas, and has gone through three stages of “passive prevention, active treatment and green use”. The monitoring and warning technology of dynamic disaster can predict the probability of disaster occurrence in advance, and the accuracy of predicting no dynamic disaster can reach 100%. The accuracy rate of power disaster is 80%, so that gas disaster can be prevented and controlled; The efficient anti-reflection extraction technology of gas in low-permeability coal seam reduces the gas treatment cycle from 24 months to 8 months, and the cost of gas treatment for tons of coal is reduced by 60%. The integrated green development and utilization technology of gas “extraction – power generation – refrigeration” can effectively
