Abstract: this paper is mainly based on coal mining face 5327 ulam actual mining processIn the process of meeting for leakage top situation analysis, some similar workingThe work experience. For better utilization of coal mine ulam equipment safetyAdopt ulam field of no.3 coal seam extraction efficiency, improve the expensive technology experience accumulated.Keywords: fully-mechanized coalface chips for leaking roof preventive measures或者Abstract: By 5327 Ulan Coal mining process over the actual coal faceEncountered in the process of spalling, roof leakage analysis of the circumstances, draw some caving workFace experience. Ulam better for the future use of coal caving safety equipment to openUlan Coal Mining Mine No. 3, to improve the efficiency of accumulation of mining the valuable technical experience.Keywords: caving face spalling preventive measures of roof
Make a summary: Have analysed , have reached some mainly by the fact that the condition exploiting the gang of movie coming across in process , leaving out the top is in progress to Wu Lan coal mine 5327 stopes reality to put the work experience putting in face together. Be that the days to come the Wu Lan coal mine is much better make use of a heddle to put in equipment safety exploiting Wu Lan well-field coal seam 3 , improve backstoping efficiency accumulating expensive technical experiences of guarantor. Keywords: The heddle puts in the face gang of movie miss and not being equivalent to precautionary measure希望能帮到你！~~
