摘 要:针对矿井作业环境粉尘污染日益严重,且现有技术手段防治难、协同弱、效果差等问题,为了从源头上实现矿井粉尘的高效控除,改善矿井作业环境、保障作业人员身心健康,对矿井开采、掘进以及运输等3个典型作业环节的粉尘防治技术装备进行了系统研究开发,提出了金属矿采场多组份水炮泥抑尘、煤矿综采面封闭雾化控除尘、金属矿掘进巷道粉尘净化、煤矿综掘面风雾双幕协同增效控除尘以及矿井皮带运输转载点干雾降尘等高效技术装备体系,结合现场试验和工业应用,对所研发的系列技术装备性能进行了对比分析。研究表明:与普通水炮泥相比,多组份水泡泥对总尘、呼尘的抑尘效果分别提高了90%、80%以上;煤矿综采面雾化封闭控除尘技术装备在现场应用后,工作面平均总尘、呼尘降尘率均大于90%;金属矿掘进巷道粉尘净化系统的除尘效率高达91%以上,净化后的风流能够进入循环通风系统,有效提高矿井风流利用率;煤矿综掘面风雾双幕协同增效控除尘装备对总尘、呼尘的平均降尘率分别能够达到97.78%、98.13%;干雾降尘装置具有良好的降尘效率,在皮带运输转载点的降尘效率达到80.4%,在溜煤眼转载点处的降尘效率达到81.8%。In view of the increasingly serious dust pollution in the mine operation environment and the problems of difficult prevention and control,weak coordination and poor effect of existing technical means,in order to realize the efficient control and removal of mine dust pollution from the source,improve the mine operation environment and ensure the physical and mental health of operators,the dust prevention technical equipment in three typical operation links such as mine mining,excavation and transportation has been systematically studied and developed.High efficiency technical equipment systems such as multi-component water blasting mud dust suppression in metal mine stope,closed atomization and dust control in coal mine fully mechanized mining face,dust purification in metal mine driving roadway,wind and fog double curtain synergistic dust control in coal mine fully mechanized mining face and dry fog dust reduction at mine belt transportation transfer point are proposed.Combined with field test and industrial application,the performance of the developed series of technical equipment is compared and analyzed.The results show that compared with ordinary water cannon mud,the dust suppression effects of the new multi-component blister mud on total dust and exhaled dust are increased by more than 90%and 80%respectively.After the on-site application of atomization closed dust control technology and equipment in fully mechanized coal mining face,the average total dust and exhalation dust reduction rate of working face are more than 90%.The dust removal efficiency of the dust purification system of metal mine excavation roadway is more than 91%.The purified air flow can enter the circulating ventilation system to effectively improve the utilization rate of mine air flow.The average dust reduction rates of total dust and exhaled dust can reach 97.78%and 98.13%respectively.The dry fog dust reduction device has good dust reduction efficiency,which reaches 80.4%at the belt transportation transfer point and 81.8%at the coal ch
