本技术属于支护施工领域,涉及一种临时支护装置,特别涉及一种掘进工作面临时支护装置。
技术介绍
地下工程施工中,支护施工耗时长,危险系数高,是事故高发环节。妥善解决支护施工技术问题,有利于地下工程安全生产。近年来,支护设备取得了显著进步,机械化水平进一步提高,但是随着我国地下工程施工越来越多,尤其是煤矿井下巷道施工,遇到的地质条件越来越恶劣,现有支护设备还不能满足支护要求。对于围岩较为破碎的巷道,顶板和工作面常常发生落石伤人。为此,《煤矿安全规程》中特别规定:掘进工作面严禁空顶作业;打锚杆眼前,必须首先敲帮问顶,将活矸处理掉,在确保安全的条件下,方可作业。巷道掘进工作面临时支护是防止顶板和工作面围岩变形和冒落的有效手段。文件1(专利申请号201610128082.7)公开了一种掘进工作面纵梁交错支撑式临时支护方法,它是通过临时支护支架实现的,所述的临时支护支架包括四柱式前架、四柱式后架、推移千斤顶和液压系统,其中前架和后架由四个伸缩式液压立柱、两个底座和顶梁组成;顶梁包括两根横梁和若干纵梁,纵梁内设有伸缩式前探缩梁;通过操作液压系统实现液 ...
