| In the process of underground mining workers,the sudden emergence of excessive gas emission problems,seriously affects the health of underground workers and mine of the safe production in Kailuan Group Lujiatuo coal mine 5831 belt Shimen,5832 track stone gate and the contact between them Lane.This paper collects and sorts the data of 5831 belt Shimen,5832 Shimen and 12 coal seam of Kailuan Group Lujiatuo Mine to find out the various influence factors of gas occurrence and the influence factors of gas occurrence reason.Then,according to the actual situation of site gas deposit and emission,to study the principle of gas storage.At the same time,the gas pressure and the related parameters of 12 coal seams and 5831 belt Shimen and 5832 Shimen rock lane are measured and studied.Finally,a series of measures are adopted to control the coal mine 5831 belt Shimen,5832 track stone gate and the contact between them Lane of gas emission from Lujiatuo mine through the measures of gas emission.Through the investigation and analysis of the effect of prevention and treatment,these methods are very good to achieve the effect of gas concentration on the mine site gas control research,have some reference value. |
