Fine management of gas drainage in coal mine

Abstract

Through the effect evaluation system of coal and gas co-extraction, gas extraction pipeline monitoring system, gas disaster warning system, ventilation monitoring and decision-making system, etc., the effect evaluation of coal seam extraction can be realized, and the comprehensive parameters such as gas concentration, flow rate, temperature and pressure of each main, trunk and branch pipelines can be monitored online in real time. Online early warning analysis of underground coal mine gas, geological structure, coal seam occurrence, ventilation and management, and online dynamic monitoring and abnormal alarm of wind speed, air volume, wind direction and other parameters in each wind location, to ensure efficient and precise extraction of gas and efficient coal mining in the fourth and fifth panels.
