液压支架为综放工作面的关键设备,它的正常工作与否,直接影响矿井的安全生产效率。受综放工作面采动影响,回采顺槽容易出现底鼓或顶板下沉现象,给周边设备运行及维护带来较大的难度,为解决以上问题,应尽量减少回采顺槽内设备配置,将乳化泵站及供电设备移出采动区,实现远距离供电与供液成为解决此类问题的新思路,主要对煤矿综放工作面液压支架远距离供液管路选型方案进行分析,并以新疆某矿1103综放工作面为例,在特定供液流量的情况下,分析不同的管径、管路数量对液压系统压力造成的影响,并提出合理有效的主供液管路选型方案。
Hydraulic support is the key equipment of fully mechanized coal caving face, its normal work or not, directly affect the mine safety production efficiency. Affected by the mining of fully mechanized top coal caving face, the phenomenon of bottom drum or roof sinking tends to occur in the backhoe, which brings great difficulty to the operation and maintenance of the surrounding equipment. To solve the above problems, the equipment configuration in the backhoe should be minimized, The emulsification pump station and power supply equipment move out of the mining area to achieve long-distance power supply and liquid supply as a new idea to solve such problems, mainly for long-distance coal mine hydraulic support face mechanization options for the pipeline analysis and Taking a 1103 fully mechanized coal caving face in a mine in Xinjiang as an example, the influence of different pipe diameters and pipelines on the pressure of hydraulic system is analyzed under the condition of specific fluid flow, and a reasonable and effective selection of main liquid supply pipelines Program.
