The automatic backfill control system installed and commissioned by JCHX at Caijiaying Zinc Mine for Hebei Hua’Ao Mining Limited was successfully accepted and highly recognized by the inspection team consisting of both Chinese and foreign experts.
The owner of the project – Hebei Hua’Ao is a sino-foreign joint venture controlled by the foreign party. The backfill plant is designed with 540,000 m3/a capacity using unclassified cemented tailings and paste pumping technique. The scope of work mainly covers configuration, installation and commissioning of instruments, automatic control system and monitoring system for the new backfilling plant.
A special work group was formed to engage in the bidding process as the leadership of JCHX’s Technological Innovation Department attached great importance to the project.
During the bidding stage, group members carefully reviewed the RFQ documents and engineering drawings, accurately analyzed and estimated the cost, proposed optimal construction scheme and competitive prices, owing to which JCHX successfully won the bid.
In the execution of contract, the project team actively communicated with the owner, made rational work schedule, developed measures for priorities and challenges in advance, prepared adequate PPE for labor and took preventive measures against unexpected incidents. During commission, value-added services were provided to the owner, such as debugging of thickener, installation, and programming of control system, etc.
After completion of the project, a long-term maintenance contract for auto-control system was signed between both parties, demonstrating the high recognition of the owner on the technical advantages and work quality of JCHX.
