| The support of the soft laneway is an important but complicated technique problem in coal mining system and rock engineering field in future. With the intensity and depth of mine scale enlarging, the problem of the timbering and the maintenance of weak-rock laneway are becoming more and more aculeate. In many mine of our country, it is the key of restraining the mine technological development and the safety in production. Thus it can be seen, the research of composite shoring about soft rock and deep laneway with high stress of Xue cun mine has the extremely significant theories meaning and value about the engineering.This text study the deep well critical depth of Xuecun, analyses the engineering geology characteristic of substation and water pump house in third level of Xue cun mine, so that it indicate it belongs to the soft and deep laneway with high stress.At the substation and water pump house in third level of Xue cun mine, account the rock physical mechanics experiment, the simulation experiment of similarity material and the computer value simulation in detail, this analyze characteristic and the mechanism of the soft and deep laneway, this also analyze the factor of cause the laneway break. Then lucubrate the mechanism of the combined supporting of soft rock which is made of blot-net-cable, the reinforce of grouting and the control of heaving floor.Scientific account the composite supporting of soft rock which is made of blot-net-cable , grouting and anti-end arch, particular introduce the mineral press observe and the arrange of measure point at the substation and water pump house in third level of Xue cun mine, deep analysis the result of mineral press observe.It proved that the laneway under high stress and deep condition uses the composite supporting of soft rock which is made of blot-net-cable , grouting and anti-end arch may control the stability of soft roadway well, and obtains the quite satisfactory effect on technology and economic.
