Practice of continuous face expanding technology in irregular fully-mechanized mining face with complex conditions
In the long-term mining process,many mines have formed residual coal resources with different forms.These residual coal re-sources cannot be arranged in a formal working face due to various changes in occurrence conditions,difficult mining techniques,and poor safety.In order to improve the recovery of coal resources,the mining plan made in the residual coal area will form various irregular working faces,it is of great significance to solve the practical problems of support transportation,installation and chute installation quick-ly and efficiently to ensure the sustainable,safe and efficient development of mine.
