综放工作面的尘源中采煤机的产尘约占总尘量的一半左右。兖州矿业(集团)公司兴隆庄煤矿开展了综放工作面采煤机 负压二次降尘装置的现场研究与应用,比较有效地解决了采煤机的产尘问题,明显地改善了采煤工作面的劳动环境。 考虑到综采工作面采煤机的工作状况和实际生产的需要,降尘装置采用分体式,即在采煤机两端各装一个负压除尘装
The dust from coal mining face in the fully mechanized top coal caving face accounts for about half of the total dust. Xinglongzhuang Coal Mine of Yanzhou Mining (Group) Co., Ltd. carried out on-site research and application of double-stage dust reduction device for coal-mining machine in fully mechanized top-coal caving face, solved the dust production problem of shearer more effectively, and obviously improved the coal mining work The working environment. Taking into account the working conditions of fully mechanized face coal shearer and the actual production needs, dust separation device used split, that is, at both ends of the shearer fitted with a negative pressure dust removal device
