MG650/1630-GWD shearer control system design

华阳一矿现有MG650/1630-GWD型采煤机在工作过程中主要依靠操作人员结合煤层分布情况对截割滚筒进行高度调整,调整精度不高,且耗时多、劳动强度高,一旦出现失误,会造成触顶事故,不利于煤矿高效安全生产。因此,需要对采煤机进行技术改造,设计采煤机自动控制系统,基于采煤机总体结构及工作流程,进行采煤机主要部件选型和控制系统设计。为验证采煤机结构与控制系统的应用可行性,采用工业性应用试验开展系统应用分析。结果表明,系统可满足采煤机控制的基本功能要求,采煤机操作人员由原来每班4人,减少为每班3人,每天人工成本减少3人,劳动强度下降,设备故障率降低,采煤效率提高5%,经济效益可观。

The existing MG650/1630-GWD shearer in Huayang No.1 Coal Mine mainly relies on the operator to adjust the height of the cutting drum in combination with the distribution of the coal seam during the working process.The adjustment accuracy is not high,and it is time-consuming and labor-intensive.Once an error occurs,it will cause a roof accident,which is not conducive to the efficient and safe production of coal mines.Therefore,it is necessary to carry out technical transformation of the shearer,design the automatic control system of the shearer,and select the main components of the shearer and design the control system based on the overall structure and working process of the shearer.In order to verify the application feasibility of the structure and control system of the shearer,the industrial application test is used to carry out the system application analysis.The results show that the system can meet the basic functional requirements of shearer control.The shearer operator is reduced from 4 people per shift to 3 people per shift,the daily labor cost is reduced by 3 people,the labor intensity is reduced,the equipment failure rate is reduced,the coal mining efficiency is increased by 5%,and the economic benefit is considerable.
