Discussion on the Treatment Scheme of Underground Heat Damage in Coal Enterprises
All the mines in Ningdong mining area of Ningxia have gradually entered the stage of deep mining,and some of the mines have appeared the problem of heat damage to varying degrees.Taking the 13/14 mining area of No.1 well of Yangchangwan coal mine as an example,the causes of underground heat damage,calculation of cooling capacity,cooling method,equipment layout and other aspects were analyzed and studied.Combined with the actual production conditions of the mine,according to the principle of overall design and step-by-step implementation,the underground centralized cooling method and ground heat removal scheme were determined to build refrigeration chamber and ground cooling system in the 13/14 mining area.Through the analysis and discussion of the technical content,this paper provides a complete set of technical system scheme for other mine thermal damage control,so as to improve the operation and management ability of coal mine thermal damage control and reduce coal mine accidents.
