 Coal Operations: • For coal mining, the trial run of the “Top Coal Caving Mining Technology” in Baode Mine at Shendong Mines was successful, increasing the recovery rate of the working face from 60% to 89%, and the trial application was also commenced; the trial run of the “Thin Coal Seam Automated Mining Technology in Shendong Mines” at one working face was completed, attaining initial success; achievements of the “R&D of Pre-warning System for Open Cut Mine Transportation Vehicles in Heidaigou” were applied on full scale, avoiding the occurrence of traffic accidents; • For upgrade of coal quality, two trial operations of the “Development and Construction of Industrial Trial Line for Low Calorific Value Coal Quality Upgrade and Processing” were commenced which raised the calorific value to 4,900 kcal./kg, effectively enhancing the utilization value of the low calorific value coal;
• For integrated utilization, significant breakthrough was made in the “R&D of Fly Ash Integrated Utilization Industrial Technology System in Zhunge’er Mines”, producing metallurgical alumina of the national standard (First Class) with a production cost lower than that applying the traditional technology in the production of alumina;
• With respect to facilities localization, satisfactory performance was achieved in the trial run of the domestic continuous miners with a monthly average recovery progression of 1,000 meters and a mining capacity of approximately 30,000 tonnes; in respect of the “7-meter Hydraulic Supporter and its Supportive Equipment” project, the design of the domestic 7-meter supporter and the research of prototype were completed; the domestic electro-hydraulic control system was successfully applied in two working faces in Tanggonggou Mines where its failure rate and part replacement rate were lower than those of the imported electro-hydraulic control system during the period.
Transportation Operations:
• Interim progress was made in the “Research on Small Radius and Reverse Curve Rail Wear Principle and Fast Detection Technology” project, which fully resolved the rail wear problems and enabled fast detection to prevent railway accidents;
• Acceptance check for the “Integrated Simulation Training System for Rail Transport” was completed, filling the gap of China in the development of such area and enhancing the operational and management training standards of our railway workers.
Power Operations:
• 10,000-tonne grade low temperature multi-effect seawater desalination technology and equipment were successfully developed with independent intellectual property rights, producing a seawater desalination equipment with a daily production capacity of 12,000 tonnes desalinated water and realizing its saturated capacity;
• Achieved success in the “Research on Application of 500KV Line Series Compensated Transmission and Sub-synchronous Resonance Suppression Technology”, realizing tentative steady operation.
