Two S&T Achievements led by JCHX, namely Research on Key Technique in Construction & Maintenance of Bottom Structure in Block Caving Method and Efficient Drill and Blast Technique in Drift Development & Research and Application of Corresponding Process in Phosphate Mines, were unanimously approved by CNIA.
        Upon arrival, the delegation was warmly welcomed by Chairman Wang Xiancheng, who extended heartfelt gratitude to Mr. Jia and other experts for the kind support, and expressed sincere anticipation for any constructive feedback from the authoritative voices.
        The experts weighed each word of the reports in the meeting, after detailed examinations and discussions the two achievements were highly recognized by the experts, and further suggestions were given for subsequent studies.
        Research on Key Technique in Construction & Maintenance of Bottom Structure in Block Caving Method completed by JCHX Mining together with Diqing Nonferrous, analyzed in detail on how to maintain the stability of bottom structure in face of the challenging orebody thickness and occurrence elevation in Pulang Copper Mine. In order to facilitate large-scale and frequent drill & blast requirements in Kaiyang Phosphate Mine, Efficient Drill and Blast Technique in Drift Development & Research and Application of Corresponding Process in Phosphate Mines, was completed by JCHX Mining, through which large-deep parallel cut hole blasting technique, and a highly mechanized drifting process relying on drilling jumbo were developed, which not only improves excavation efficiency but brings Chinese mining technology up to the international level.
