Summary: 湖北巴东的9个月累计项目在采矿创新方面取得突破，效率提升67%，实现10公里智慧隧道建设以及绿色能源整合，树立了新的行业标杆……

湖北巴东900万吨/年（T/Y）骨料项目是湖北省的重点省级项目。该项目总投资为16亿元人民币，主要包括采矿区、骨料加工系统和预制工业园区。一旦投产，采矿系统预计年产能为900万吨，产能为每小时3000吨，预计年产值在3亿到5亿元人民币之间。

该项目涵盖整个产业链，包括采矿、骨料加工与运输以及预制混凝土构件的生产。一项限制项目整体产能的关键工程设施是连接骨料加工区与筛分存储区的10公里小直径运输隧道。

优化设计以提高施工效率

在初步设计阶段，项目团队邀请业主参观类似项目进行现场考察

To address the tight schedule for the 10-kilometer long tunnel, the project team adopted a "branch tunnel + main tunnel" three-dimensional construction network, increasing the number of work fronts to enhance construction efficiency. The project team identified four areas with stable surrounding rock and gentle terrain to set up branch tunnels, forming six operational starting points: two main tunnel entrances and four branch tunnel entrances. Each operational front is equipped with a specialized team, implementing a "two-shift" work schedule, with a maximum daily advance of 17 meters. Additionally, each work front is provided with a customized "small equipment package," including small excavators, small dump trucks, custom-made mobile carts, and small loaders, effectively ensuring progress while avoiding resource waste caused by oversized equipment.

多维安全保障，提升施工安全

In response to the high-risk environment, the project team established a comprehensive safety net involving "monitoring, early warning, and response." A "leadership on duty" system was implemented, requiring on-duty leaders to conduct daily inspections at each working face, focusing on surrounding rock integrity, support structure stability and on-site safety protection facilities. This "problem-solving at the frontline" approach fosters a safety-first culture among team members, encouraging them to prioritize safety over production and creating an atmosphere where management leads in hazard identification and operational teams proactively manage risks.

An expert consultation mechanism was also established, with multiple visits from the company's safety supervision department, technology department, and design institute experts to conduct "safety check-ups." Special plans were developed for eight high-risk sections to ensure smooth construction in these areas.

Multi-Dimensional Protection to Ensure Construction Safety

刷新项目进度流程管理

为进一步加快施工进度，项目组详细制定了进度管理，明确了钻孔、爆破、挖方和支护的时间安排。每个作业面都配备

为了解决喷射混凝土支护时间过长的问题，团队将单枪喷射混凝土机替换为双枪喷射混凝土机，并优化了混凝土配比，将支护时间从 4 小时缩短至 2.5 小时。三层围岩段的日循环次数从 2 次提高到 3 次，日推进量从 6 米提高到 9 米。该项目成功地在 18 个月内完成了 10 公里隧道的开挖和支护，创造了新的纪录，并跻身行业一流。

全周期增值运营规划

运营阶段的成本控制和价值提取对于整个项目生命周期的综合效益至关重要。项目团队在建设阶段整合地质数据和设备运行参数，主动规划，建立了“隧道结构、运输设备和加工单元”三元监控系统。季度进行全面检查，将维护成本转化为预防性维护。

此外，实施了备件集中管理系统，与设备制造商合作建立“区域共享备件库”。高频易损件集中采购并统一分配，减少库存积压，降低备件相关的资本成本。

为降低物料处理系统破碎筛分设备的用电成本，项目组预先规划了峰谷电价策略，动态调整设备星级

By ensuring seamless coordination between the construction and operational phases, the project team continually promotes cost reduction and efficiency enhancement through systematic thinking, embedding "cost-effectiveness" into the project's management DNA. This meticulous cost control and focus on tangible benefits contribute significantly to the company's high-quality development.

资源和能源整合拓展价值空间

Leveraging the project's mining resources and regional energy demands, the project team collaborated with the company's energy sector to advance the "mining-energy integration" pilot project. Utilizing idle land in the mining area, a distributed photovoltaic energy storage system was planned to cover electricity needs for processing and office areas, potentially reducing external electricity costs by millions of RMB and achieving dual benefits of "green energy generation and cost reduction."

考虑到矿区到加工区存在严重的矿物下坡运输特性，以及电动矿车相较柴油车辆的成本优势，该项目计划采用电动矿车进行原物料运输，从而大幅降低运营运输成本。
