Rational Support Technology of Roadways Driving Along Next Goaf in Two Sides of Isolated Fully Mechanized Caving Face

Aiming at the supporting problem of difficult maintainence of roadway caused by rock pressure increasing during mining process of isolated fully mechanized caving face,this paper investigated the failure mechanism of the isolated fully mechanized caving face by field research of loose circle,put forward one body support method with wire meshes and cable anchor,and carried out the field industrial test.The results showed that the displacement of roof,floor and two sides of roadway was very small during excavating(within 160 days) in this support way,and the deformation became larger during the mining of working face,but the total amount of deformation was still small,which provided good conditions for smooth mining and personnel safety.
