Mine water prevention and control technology based on analytic hierarchy process and fuzzy evaluation method
In order to improve the water prevention and control technology of non-coal mines,improve the environment of mine working face and ensure the safe production of non-coal mines,we take Mingniwan Phosphate Mine as the engineering background,and use the analytic hierarchy process to analyze the three major factors and 12 minor factors affecting the water prevention and control of the mine.The combined weight of each factor relative to the optimal evaluation scheme is ob-tained,and the fuzzy evaluation method is used to evaluate the technology currently implemented in the mine,and the opti-mization direction of the water prevention and control technology is obtained.The conclusions are as follows:the mine drain-age system is the biggest factor affecting the water control effect of the mine,The next is the system of mine water prevention and control,and the final is water prevention and control work on the surface.Among the 12 influential factors,the biggest is mine water discharging system,and the most minor is the setup of discharging channel and water-blocking wall.The water prevention and control technology is optimized from three aspects of water exploration and discharging technology,crack-fill-ing technology and roadway driving to provide an improving direction for the mine water prevention and control and reference for other mines with similar geological conditions.
