Abstract
In view of the problems such as obvious mine pressure behavior,large deformation amount of the roadway,difficulty in maintenance,inability to meet safety production needs and others in the deep mining area of Chensilou Coal Mine,an analysis is conducted on the roadway layer position,surrounding rock conditions,compressive strength,existing support strength,mechanism and types of roadway failure of the pump room in the ninth mining area.The"anchor rack injection"collaborative support technology is adopted for maintenance and reinforcement.After governance,the pump room in the ninth mining area does not show any phenomena such as heaving floor,wall caving,roadway obvious convergence or others,meeting the normal drainage needs and providing technical support for roadway support in the subsequent deep mining area.关键词
