通过长距离软管通风技术的试验研究，提出了“调整布局、合理匹配、防漏降阻、严格管理”的综合治理措施，采用国产88－1型通风机，及国产长丝涤纶纤维增强型胶布研制1．2m大直径软质风管，改进了接头型式，在国内首次实现了单机软管有效通风距离达到2000m，技术检测和。程实践表明，。作环境显著改善，主要指标达到国家劳卫标准的要求，百米漏风率降到l％一3％，排烟和出渣工序作业时间显著缩短，加快了施工进度，满足了工程建设的要求．
Through the experimental research of long-distance hose ventilation technology, put forward the comprehensive control measures of “adjusting the layout, matching reasonably, preventing leaks and reducing the resistance and strictly managing”, adopting domestic type 88-1 ventilator and domestic filament polyester fiber reinforced Adhesive developed 1.2m large diameter soft duct, improved connector type, the first time in China to achieve a single hose effective ventilation distance of 2000m, technical testing and. Practice shows that. For the major environmental improvements, the main indicators meet the national standards for labor and health standards, air leakage rate down to 100% l3%, smoke exhaust and slag process significantly shorter operating time, speeding up the construction schedule to meet the construction requirements.
