| Abstract: | Roadway support is one of the difficulties in safe construction and production of coal mines.In the paper,in order to solve the problem of difficult supporting large section roadway driving along goaf in deep mine,on the basis of numerical simulation of support effect and mechanism of fortified roadways at their different parts,the concept of floor distortion control in the whole section of large section roadway driving along goaf in deep mine was brought forward.It refers to"fortifying roof,supporting side-walls and fortifying floor of the roadway".The method has been applied to engineering practice,showing good technical and economic effect. |
