为了认识永川煤矿三叠纪上统须家河六段(T_3xj~6)地层砂岩的力学性质和冲击倾向性,以美国MTS815岩石力学测试系统作为动力设备,对砂岩力学性质和冲击倾向性进行了测试,并利用Origin7.5中的面积工具箱对冲击倾向性指标进行了计算,避免了曲线下面积计算不准确的缺点.实验研究结果表明:永川煤矿T_3xj~6砂岩具有杨氏模量较低、强度不高、变形曲线上的塑性变形表现不明显的力学特性;T_3xj~6砂岩具有冲击倾向性,但是冲击倾向性整体上较弱,局部有强烈冲击倾向性.研究结论为永川煤矿延深工程过三叠纪上统须家河六段(T_3xj~6)砂岩体发生动力灾害的治理工作提供了理论基础.

In order to understand the mechanical characteristics and burst-prone nature of Upper Triassic Xujiahe(T_3xj~6)sandstone in Yongchuan coal mine,experiments were conducted using MTS815 rock testing system made in US.Indexes of burst-prone were analyzed using the area tool in Origin7.5,which avoided the shortcomings of low precision in area calculation under peak.Results of the experiments indicated that the T_3xj~6 sandstone has low mechanical characteristics,showing a low Young's modulus,medium strength and plastic deformation.T_3xj~6 sandstone was burst-prone,but normally fair and locally intensive.The research provided a theoretical basis for hazard treatment of T_3xj~6 sandstone in Yongchuan coal mine.
