莒山煤矿3号煤层综放工作面液压支架选型

Selection of Hydraulic Support for Fully Mechanized Caving Face in No.3 Coal Seam of Jushan Coal Mine

以莒山煤矿f3101工作面为工程背景,分析了工作面支架的架型、支护高度范围、支护强度、工作阻力等关键技术参数,确定了工作面使用ZF4800/17/28型四柱支撑掩护式支架,并通过工程实践对其应用效果进行了分析。实践表明,ZF4800/17/28型液压支架的使用效果良好,可满足工作面安全生产要求。

Taking the caving face f3101 of Jushan Mine as the engineering background,the key technical parameters such as support type,support height range,support strength and work resistance have been analyzed.It has been determined that ZF4800/17/28 four-pillar shield support can be used in caving face,and its application effect had been analyzed through engineering practice.Practice showed that ZF4800/17/28 hydraulic support had good application effect and could meet the safety requirements of caving face.
