An integrated technology package was built for safe, efficient, and continuous mining in a deep, massive, and complex nickel and cobalt mine. This was done by the invention of a large-area continuous mining method with honeycomb drives; the establishment of ground control theory and a technology package for high-stress and fragmented ore rock: and the development of a new type of backfilling cement material, along with a deep backfilling technology that comprises the pipeline transport of high-density slurry with coarse aggregates. In this way, good solutions to existing problems were found to permit the efficient exploitation and comprehensive utilization of the resources in the deep Jinchuan nickel mine. In addition, a technological demonstration in an underground mine was performed using the cemented undercut-and-fill mining method for stressful, frag- mented, and rheological rock.展开更多

Methods: A total of 100 cases of CFS patients were evenly randomized into treatment group and control group which were treated with elongated needle puncture of ST 36 and CV 6 plus nursing and oral ackninistration of Shiquan Dobu Tong (十全大补汤 Decoction of Ten Powerful Tonics) separately. Acupuncture and medication were given once daily, with 7 sessions being a therapeutic course, 4 courses altogether. Results: After 4 courses of treatment, of the two 50 cases in treatment and control groups, 4 (8.0%) and 2 (4.0%) were cured, 37 (74.0%) and 16 (32.0%) experienced marked im- provernent, 6 ( 12.0 % ) and 19 (38.0 % ) had improvement, 3 (6.0 % ) and 13 (26.0 % ) tailed, with the total effective rates being 94.0% (47/50) and 74.0% (37/50) respectively. The total effective rate and markedly effective rate of treatment group were significantly higher than those of control group (P〈0.05, 0.01). Conclusion; Deep puncture of Zusenli (ST 36) and Qihai (CV 6) with elongated needle combined with comprehensive nursing has a definite therapeutic effect in the treatment of chronic fatigue syndrome.展开更多
