Roof Control Technology of Fully-mechanized Mining Face
The roof control of fully-mechanized mining face is very important for safe mining.Combined with the actual situation of 407 working face,the roof control technology used in the mining process was analyzed.Firstly,the support design of the working face roof was carried out,including the determination of support equipment and support strength;then,the roof control methods used in the mining process were discussed,including the roof management end support,advance support and unanchoring process method;finally,the content and methods of ore pressure observation in mining process were discussed,and the mine pressure was analyzed.It can provide some technical reference for the roof control in the process of fully-mechanized mining face.
