根据张集煤矿1112（3）孤岛工作面煤层赋存条件，为保障该工作面顶板回采安全，针对试验巷道 U 型棚段不同变形情况采用了不同加固支护参数，建立3种工况的力学模型，进行了应力、位移和塑性区分析。结果表明，巷道总体变形在合理范围内，局部稍加卧底即能满足安全生产要求。
根據張集煤礦1112（3）孤島工作麵煤層賦存條件，為保障該工作麵頂闆迴採安全，針對試驗巷道 U 型棚段不同變形情況採用瞭不同加固支護參數，建立3種工況的力學模型，進行瞭應力、位移和塑性區分析。結果錶明，巷道總體變形在閤理範圍內，跼部稍加臥底即能滿足安全生產要求。

According to the coal seam occurrence conditions of the 1112(3)isolated island working face in Zhangji coal mine,in order to ensure the security of the mining face roof,different supporting pa-rameters are used based on different deformation conditions of the U-type tent period of the experimental roadway.Mechanical models under three kinds of working conditions are established,and the stress,dis-placement and plastic zone are analyzed in depth.The results show that,the overall deformation of road-way is in a reasonable range,it can satisfy the requirements of safety production by local restorat on of roadury floor.
