掘进机综采中截割控制系统的优化分析

Optimisation Analysis of the Cut-Off Control System in Integrated Mining of Roadheaders

在矿采机械化水平不断提高的背景中,要求各煤矿结合实际开采工况对掘进机的截割控制系统进行优化,不断提高掘进机的自动化程度。某矿开采中,由于受井下多方面因素干扰,掘进机截割系统中的截割方式存在不足,为了保证该矿主采2110综采面的开采进度,需要应用自动截割理论,分析“S”形截割方式的应用。为此,在概述案例煤矿后,先分析截割控制系统中自动截割的优化方案,然后讨论不同岩性下掘进机的截割尺寸,以期可以提高掘进机的截割效率,保证综采效率。

In the background of the continuous improvement of mining mechanisation,coal mines are required to optimise the cutter control system of the roadheader in the light of the actual mining conditions,so as to continuously improve the automation degree of the roadheader.In a certain mine,due to the interference of many underground factors,the cutting method in the cutter system of the roadheader is insufficient,in order to ensure the mining progress of the main mining face 2110,it is necessary to apply the theory of automatic cutting and analyse the application of the"S"cutting method.To this end,after an overview of the case mine,we first analyse the optimisation of automatic cutting in the cutting control system,and then discuss the cutting dimensions of the roadheader in different lithologies,in order to improve the cutting efficiency of the roadheader and ensure the efficiency of integrated mining.
