掘锚机掘进过程整机后退机理及防治措施研究

Research on Mechanism and Prevention Measures of the Whole Machine Retreats in the Driving Process

本文针对某矿掘锚一体机掘进过程中出现整机后退问题进行了分析,并根据问题的分析提出掘锚一体机防退机对策。依据现场退机现象,进行设备故障排查,理论计算分析退机现象,提出掘锚一体机防退机对策,主要对策有:采用“顶天立地”支撑结构、加大护盾支撑压力度、护盾顶板增加防滑齿、匹配掏槽速度和切割速度等。This paper analyzes the problem of whole machine backing up in the course of driving and anchoring integrated machine in a mine, and puts forward the countermeasure of preventing the machine backing up. According to the phenomenon of machine withdrawal on the spot, the equipment failure is checked, the phenomenon of machine withdrawal is calculated and analyzed in theory, and the countermeasures for preventing machine withdrawal of the driving and anchoring integrated machine are put forward, the main countermeasures include adopting “Not Scared to Die” supporting structure, increasing shield support pressure, increasing anti-skid teeth on shield roof, matching cutting speed and cutting speed.
