山东煤矿粉尘综合防治技术创新与实践

Innovation and practice for the prevention and control technologies of coal dust in Shandong coal mine

随着山东煤矿采煤机械化程度的提高和开采强度的加大,生产性粉尘危害日趋严重,严重威胁着矿井生产安全和职工身体健康,尘肺病多发趋势并未得到有效遏制。近年来,山东煤矿为有效降低井下作业环境中的粉尘浓度,减少粉尘危害,在严格落实国家有关粉尘防治管理规定的同时,积极探索粉尘防治技术,从"防、治、护、管"四个环节重点突破,特别在煤层短壁注水、旋转喷雾、降尘添加剂、高效防尘口罩、强化管理等方面,形成了一套切实可行、可靠、有效的粉尘综合防治办法,为企业开展粉尘防治工作提供一定的经验借鉴。

With the improvement of mechanization level and the increase of mining intensity of coal mining in Shandong,the hazard of productive dust has become increasingly serious,with great threat to the mine work safety and worker health,and the prone trend of pneumoconiosis has not been effectively contained. In recent years,To effectively reduce the dust concentration in underground work environment and reduce dust hazard,with strictly implementing the relevant state management regulations on dust prevention and control,the dust prevention and control technologies have been actively explored in Shandong coal mine. The key breakthroughs have been taken from four stages 'prevention,management,protection and management',and a set of feasible,reliable and effective dust comprehensive prevention and control measures were formed,especially in the aspects of short-wall water injection in coal seam,rotating spray,dust additives,efficient dust mask,strengthen management etc. The advanced dust control technologies in Shandong were analyzed and summarized in this paper,which is worth popularization and application.
