摘要:
为了解决桃山三井工作面充填开采过程中出现的堵管以及管道的高磨损率等问题,运用流体力学和采煤学,结合该工作面的实际情况,采用自流+泵送的管道输送技术进行了工业试验,并利用ANSYS模拟分析了在工业既定速度2.0 m/s时不同料浆浓度、管径对全程管压的影响。模拟结果表明:在既定输送速度下,管压在合理的可控范围内且易于输送时的充填料浆浓度、管径取值范围分别为52%,140~180 mm时,此时的输送管压分别为134.561 kPa,130.053~138.759 kPa; 利用模拟结果进行料浆输送的工业试验结果表明,堵管、管道磨损得到了解决,充填开采取得良好的效果,有效地控制了顶底板的变形,降低了顶板的下沉量,减少对环境的破坏,同时也表明该管输系统是一种“安全、经济、环保、可靠”的充填采煤系统,为该矿以及类似条件下的矿山充填开采提供了借鉴作用。
Abstract:
In order to solve the mitsui peach mountain face appeared in the process of filling wall pipe and high wear rate of the pipeline,an introduction to using the fluid mechanics and mining,in combination with the practical situation of the working face,using their+pump pipeline technology,the industrial experiment and ANSYS simulation analysis in the industry established speed 2.0 m/s different slurry concentration,the influence of the diameter for the entire pipe pressure.Simulation results show that under the given delivery speed,pipe pressure within the reasonable control and easy to transport the filling slurry concentration,pipe diameter value range of the 52%,140 to 180 mm respectively,at this time of pipeline pressure were 134.561 kPa,130.053~138.759 kPa; Slurry transportation industrial test is carried out using the simulation results show that the blocking pipe,pipe wear has been resolved,and filling to obtain good effect,effectively control the deformation of roof and floor,reduces the roof subsidence,reduce the damage to the environment,also show that the pipeline system is a kind of “safety,economy,environmental protection,reliable” filling mining system,for the mine and similar mine under the condition of filling mining provides reference.
