2-126采面选用液压支架适应性验证

Adaptability Verification of Hydraulic Support Selection at 2-126 Working Face

霍宝干河煤矿2-126工作面选用ZY9000/25.5/55型和ZY13000/26/55型液压支架进行支护,本文分别从液压支架承压、支护强度、工作阻力、初撑力、泵站供液压力、采高、底板比压等八个方面验证了支架选型的合理性。现场监测液压支架工作阻力变化,结果表明:工作面回采期间,液压支架运行良好,所选支架满足现场的安全生产需求。

The paper makes an adaptability verification of ZY9000/25.5/55-typed and ZY13000/26/55-typed hydraulic support through filed monitoring of the changes in the working resistance at 2-126 working face of Huobao Ganhe Coal Mine from eight aspects of hydraulic support pressure, support strength, working resistance, setting force, pump station hydraulic pressure, mining height, floor specific pressure, etc., whose monitoring results show that the selected support can meet the safety production requirements on site.
