摘　　要：榆树井煤矿属于典型的西部弱胶结软岩矿井,巷道受矿山压力影响变形严重。通过对围岩成分分析及巷道松动圈的测定,研究其变形机理。本次试验采用了大量矿压观测数据建立模型对数据进行回归分析,确定了巷道两帮移近量与底鼓之间呈正相关关系。通过数据表明该条件下巷道适合采用全断面锚网喷联合支护的方式,能够有效地控制巷道变形,并经实地验证取得了显著成效。Yushujing Coal Mine is a typical weak cemented soft rock mine in the west, and the roadway is seriously deformed due to the influence of mine pressure. Through the analysis of the composition of surrounding rock and the determination of roadway loose zone, its de-formation mechanism is studied. In this experiment, a large number of mine pressure observa-tion data are used to establish a model for regression analysis of the data, and it is determined that there is a positive correlation between the two sides of the roadway and the floor heave. The data show that under this condition, the roadway is suitable to adopt the full sec-tion anchor net spray combined support, and can effectively control roadway deformation, and remarkable results have been achieved by field verification.
