摘要：The deformation of soft rock roadway caused by floor heave is a major challenge for coal mines in China western mining areas. To achieve security and stability of soft rock roadway, this work considered the headgate at panel 11505 of the Yushujing Coal Mine as background. First, based on the limit equilibrium method and slip line field theory,a model of floor heave was established, the mechanism of floor heave control was analyzed, and an optimized support method was proposed. Then, the displacement, stress and failure zones around the surrounding rock with the original and optimized support were studied by FLAC. Finally, the serviceability of the support method was verified by field application. The results showed that the main deformation form of soft rock roadway is floor heave, and 0.5 m is relatively reasonable thicknesses of the inverted arch. The extrusion failure zone and shear failure zone were mainly affected by tensile and shear failure, respectively. The modification of floor and the effective support are key points. The failure zone was consistent between numerical simulation and theoretical calculation. The maximum convergences of floor heave determined by numerical simulation and field measurement were 220 mm and 240 mm, respectively, which were reduced by 55% and 60% compared with the original support, and the convergence between sidewalls decreased considerably. The optimized support method controls the floor heave well.

摘要：针对节点能量有限的无线传感器网络(WSN),设计一种有效延长网络生命时间的网络拓扑控制算法非常有必要。考虑到节点是自私的,每个节点想着如何减少自身能耗提高自身利益,却忽视了网络整体利益。为了解决该冲突,利用势博弈存在纳什均衡的性质,提出了基于势博弈的分布式拓扑控制算法(potential game and distributed topology control,PGDTC)。该算法是一种能量高效和能量平衡的拓扑控制算法。仿真结果表明:相比于现有的一些拓扑控制算法,PGDTC算法能够有效地延长网络生命时间。
