“xxxxwwww中国”四川首台矿用盾xxxxwwww中国构机入井 煤炭掘进实现智能化

  中新xxxxwwww中国网成都11月21日电 xxxxwwww中国(记者 刘忠俊)11月21日,四川省首台矿用盾构机(硬岩TBM掘进机)“川煤龙腾号”入井仪式在该省广安市举行,矿用盾构机的应用实现四川煤炭盾构掘进“零”的突破。

  入井仪式现场,一声指令下,六个专用平板车载着矿用盾构机设备缓缓驶往龙滩煤矿井下,现场欢呼声、呐喊声响起。“加快形成以盾构机为核心支撑的掘进生产体系,实现快速掘进,提高单进水平,缓解接续紧张,确保稳产达产,提高保供能力,带动其他矿井向智能化掘进迈进。”川煤集团总工程师、华荣能源公司董事长奚光荣表示。

  据了解,四川省首台矿用盾构机(硬岩TBM掘进机)建设项目,是继智能化煤矿建设项目后又一推进企业企业高质量发展的“新引擎”。此次矿用盾构机型号为EQC5030全断面硬岩掘进机,整机长度90余米,整机重量570吨,采用复合式刀盘一次破岩成洞,刀盘开挖直径为5.03米,机身搭载了4台液压锚杆钻机,3台液压超前钻机,配备了4台250千瓦的变频电机以及2台除尘风机,并有液压、自动润滑、供水冷却、除尘等系统。

  此外,该台矿用盾构机设备还能实现“同步掘进+同步支护+同步出矸”、铺底施工工艺,以及巷道80米小半径水平转弯施工功能,最大能达到100毫米/分钟的掘进速度,小班最高进尺可达28.2米,圆班最高进尺可达51米,月最高进尺可达641米,掘进效率较传统工法提升了4倍-7倍。

  据悉,矿用盾构机的应用为四川薄煤层及复杂地质条件下的煤炭掘进提供了技术支撑,也将促进(成)四川煤炭掘进模式的重大转向。同时,为保障职工生命安全、改善作业环境、降低劳动强度、增加职工工资收入、提升职工幸福指数起到了积极作用。(完)
