Practice of roof mesh laying technology for fully-mechanized mining face expansion and withdrawal
The fully-mechanized mining face enters the harvesting stage,usually starting from the closed mining to prevent the construc-tion mesh of the roof from falling off and the subsequent withdrawal of the support from the gangue and leakage.In response to the con-struction of the roof mesh for the closed mining expansion of the fully-mechanized mining face in Huangling Mining Company's No.1 Coal Mine,two roof mesh methods are introduced.By comparing the process,technology,and investment cost,the applicability of differ-ent working face conditions was pointed out,providing reference for the roof mesh for the closed mining expansion of the fully-mecha-nized mining face.
