en.Wedoany.com Reported - Recently, Changji Xuefeng in Xinjiang, China, completed a single-day blasting volume exceeding 550,000 cubic meters at the Tianchi Energy South Open-pit Coal Mine. The entire operation was conducted safely with zero accidents, featuring efficient and orderly construction, setting a new record for large-scale blasting operations in this mining area. The Changji Xuefeng project team conducted geological surveys in advance, precisely optimized blasting parameters, and completed preparatory work such as site clearance, blast hole acceptance, and explosives reserves.

The geological conditions for this blasting operation were complex. Changji Xuefeng adopted differentiated techniques for dry holes and water holes: mechanized continuous charging was implemented for dry holes to ensure uniform and standardized charging; specialized waterproof charging techniques were used for water holes to guarantee stable and reliable blasting. Stemming and network layout strictly adhered to industry standards, while detonator code scanning verification was executed to achieve full-process traceability control of explosives. Each position had clear division of responsibilities with efficient linkage, achieving standardized operations throughout the entire process.

This year, Changji Xuefeng introduced intelligent drilling rigs for large-scale mining construction, with monthly drilling volume exceeding 1 million cubic meters, significantly improving drilling precision and operational stability. Additionally, the 170mm large-diameter borehole drilling test was successfully completed, addressing technical shortcomings in large-diameter construction and accumulating mature on-site practical experience. Changji Xuefeng uses intelligent equipment throughout the entire construction process, successfully solving construction challenges under complex working conditions. Moving forward, the company will continue to refine core drilling and blasting techniques, deepen the application of intelligent equipment and technology, and uphold the red line of safety and quality.
