Construction and installation are the key links for Xinhai Mining EPC+M+O to truly realize the design and research, equipment manufacturing, which are directly related to whether the mining plant can reach the production standard.
Mine Construction
Construction scope
Xinhai Mining can provide open pits, vertical shafts, inclined shafts, ramps, roadways and chambers, risers and orepasses, cutting and filling, permanent support, water control and management, plants, and equipment foundations.
Construction principles
• Follow the construction procedures and the approved design documents;
• Adopt advanced, cost-effective, safe, environment-friendly and energy-saving technologies, equipment and materials;
• Take effective measures to improve working environments and ensure the safety and health of workers;
• Act in accordance with local laws and regulations.
Advantages of Xinhai Mining
The construction units have mine construction certificates, with relative quality, safety and environmental management systems set up at the workplace. The construction quality management and inspection system is improved, and relevant technical standards for construction are established.
The special operation personnel working in roadway construction have undergone training and obtained relevant certificates.
Full preparation before construction:
① Analyze the geological, hydrological and drilling data of shaft based on the geological and prospecting report to draw the predicted shaft profiles;
② Design details and joint checkup of construction drawings;
③ Compile and approve construction organization design or construction scheme, including the design basis, project overview, construction arrangement and schedule, construction preparations and resources arrangement plan, major construction methods, construction site layout, schedule management plan, quality management plan, safety management plan, environmental management plan, cost management plan and other management plans;
④Complete site surveying, foundation piles erection, site leveling, and the facilities for water, compressed air and power supply, communication, and fire, flood and waterlog control.
Rich experience has been accumulated in dealing with harmful geological conditions such as soft rock, fractured zone, old workings, karst cave, fault and large aquifer.
Shaft and Drift Installation
