山东丰源远航煤业有限公司北徐楼煤矿职工自行研制出一种采煤工作面回风巷捕尘器,有效降低了采煤工作面回风巷煤尘量。该矿采煤工作面在出煤期间,回风巷煤尘量增多,对在回风巷工作的职工造成健康威胁。为有效降低回风巷煤尘量,该矿采三工区职工经过反复调研,研制 Shandong Fengyuan voyage Coal Industry Co., Ltd. North Xuelou coal mine workers to develop a coal mining face return airway dust catcher, effectively reducing the coal face return airway coal dust. During the coal mining face of the mine, the amount of coal dust in the air return lane increased, posing a health threat to the workers working in the return air lane. In order to effectively reduce the amount of coal dust in the air return lane, the mine workers in the three mining areas after repeated research, development
