在煤矿生产过程中,粉尘是困扰着安全生产的重大灾害之一.对于煤矿综掘工作面粉尘防治工作,重点是针对截割产尘源.为了降低工作面粉尘浓度,改善工作面劳动环境,通过分析综掘工作面粉尘的主要来源和现场测试综掘巷道粉尘浓度的分布规律,在传统综掘工作面高压喷雾降尘的基础上,提出了2种改进的综掘工作面高效喷雾降尘方案.方案1使用增压水泵,设计一台体积小、重量轻的水泵泵组,安装在掘进机机身上,通过增压水泵的特定转换,获得高压水;方案2使用掘进机上的液压油,驱动一台以液压水泵为核心的增压泵,获得高压水.2种方案均克服了传统方法的缺点和不足,结合抑尘剂配比装置,在实际应用中取得了良好的降尘效果,降尘率最高达到了84%.
在煤礦生產過程中,粉塵是睏擾著安全生產的重大災害之一.對于煤礦綜掘工作麵粉塵防治工作,重點是針對截割產塵源.為瞭降低工作麵粉塵濃度,改善工作麵勞動環境,通過分析綜掘工作麵粉塵的主要來源和現場測試綜掘巷道粉塵濃度的分佈規律,在傳統綜掘工作麵高壓噴霧降塵的基礎上,提齣瞭2種改進的綜掘工作麵高效噴霧降塵方案.方案1使用增壓水泵,設計一檯體積小、重量輕的水泵泵組,安裝在掘進機機身上,通過增壓水泵的特定轉換,穫得高壓水;方案2使用掘進機上的液壓油,驅動一檯以液壓水泵為覈心的增壓泵,穫得高壓水.2種方案均剋服瞭傳統方法的缺點和不足,結閤抑塵劑配比裝置,在實際應用中取得瞭良好的降塵效果,降塵率最高達到瞭84%.

Dust is one of the major disasters in coal mine production process.For coal mine dust prevention and control work spray dust is very important.The main source of dust and field test the dust concentration distribution in full -mechanized excavation face were introduced,and two efficient plans for spray dust were presented.Without the traditional large volume of water tanks and complicated water control system,plan A used booster pumps to design a small size and light weight pump group,which installed on the body of machine,and got high -pressure water though the specific conversion of booster pumps.Plan B getting high -pressure water was through the hydraulic oil of the machine to drive a booster pump which based on the hydraulic pump as a core.Both schemes were overcame the shortcomings and the insufficiency of traditional methods and obtained very good dustproof effects combined with the use of additive equipment of dust suppression after application. Dust highest rate reached 84%.
