随着我国综机采煤技术的发展,与采面液压支架效能相比,采面端头支护落后的矛盾越来越突出了。当前它在一些矿区已成为影响综机采煤高产的重要因素之一,因此,研究综机采面端头支护已是迫在眉睫的问题。本文着重从端头支架功能及矿压角度,浅析几个端头支护技术发展中应注意的问题。一、端头支护的现状及存在问题正确的端头支护应能保证安全有效地维护端头围岩,使其工作状态良好。鉴于采面和顺槽支护方式及回采工艺的多样性,故且端头支护方式也是不同的。当前我国端头支护还是比较落后的。巷道端头用单体或液压支架维护;采面机头、机尾设备区用单体特殊超前支架或液压支架及时支护;煤壁前方支承压力影响区用单体点柱或抬棚加强支护;当采用沿空留巷时,煤壁后方支承压力 With the development of coal mining technology in our country, contradictions of backward support of mining face are more and more prominent compared with hydraulic support efficiency of mining face. At present, it has become one of the important factors that affect the high yield of coal mining in some mining areas. Therefore, it is an urgent problem to study the support of fully mechanized coal mining face. This article focuses on the end bracket function and mine pressure point of view, analysis of several end support technology should pay attention to the development of the problem. First, the status of end support and existing problems Correct end support should be able to ensure safe and effective maintenance of the terminal rock, so that it works in good condition. In view of the karmic and cis groove support methods and mining process diversity, so the end support method is also different. At present, our end support is still relatively backward. Roadway ends with single or hydraulic support maintenance; mining machine head, tail end of the device area with a single special advance support or hydraulic support timely support; coal wall in front of the pressure supporting area with a single point column or lift reinforcement Protection; when used for gob-side entry, the pressure behind the coal wall support
