    Constructing a safe construction management system based on multi-dimensional information technology for large chambers in ultra-deep wells

    • 摘要: 在超深井高地压大硐室掘支作业过程中,构建一套以安全为导向的施工管理模式是我国发展深部地下工程解决“向地球深部进军”难题和发展深地工程的先决条件。以采深超1 600 m的滇东北某矿风机基站硐室和1#主溜井渣仓硐室、2#主溜井渣仓硐室的作业管理为例,施工点埋深均大于1 200 m以上,硐室均为大跨度高悬挑硐室,设计采用锚喷加钢筋混凝土浇灌支护,根据不同硐室设计功能布置相关配套工程。施工过程中基于工艺甘特流程、二维设计、三维信息模型等多维信息技术构建出一套适用的滇东北某矿超深井大硐室安全施工管理体系,再通过数智管控技术进行方案选取、专业碰撞和技术验证。经实践应用,超深井大硐室安全施工管理体系在滇东北某矿的应用为我国超深地下工程积累了宝贵经验,为技术理论管理模式提供实践支撑与依据,保障了矿山的安全与生产,促进了超深井工程的发展。

       

      Abstract: The construction of a safety-oriented construction management model is a prerequisite for the development of deep underground engineering in China to solve the problem of “advancing to the depths of the earth” and to develop deep underground engineering. For example, in a mine in Northeast Yunnan Province, where the mining depth exceeded 1 600 metres, the construction site is at a depth of more than 1 200 metres, and the chambers are large-span, high overhanging chambers with anchor spray and reinforced concrete pouring support, and the associated ancillary works are laid out according to the design function of the different chambers. During the construction process, a set of safety management system is constructed based on multi-dimensional information technology, such as Gantt process, 2D design and 3D information model, which is then used to select, collide and verify the construction plan. After practical application, the application of the safety construction management system in a mine in Northeast Yunnan Province has accumulated valuable experience for China’s ultra-deep underground projects, provided practical support and basis for the technical theory management model, ensured mine safety and production, and promoted the development of ultra-deep well engineering.
