【摘要】：礦井事故極大地威脅著工作人員的生命安全和煤礦的財產安全,瓦斯事故又是煤礦事故中危害最嚴重最危險的一類。隨著開采深度的增加和工作面推進速度的加快,不少低瓦斯礦井也出現了瓦斯涌出異常的問題。因此研究低瓦斯礦井瓦斯涌出影響因素,對瓦斯涌出異常的防治有著重要意義。本文以紅石巖煤礦12406工作面為研究對象,對絕對瓦斯涌出量、上隅角和回風順槽瓦斯?jié)舛鹊挠绊懸蛩剡M行相關分析,尋找對瓦斯涌出影響最顯著的因素,并結合回歸分析,將顯著因素和絕對瓦斯涌出量、瓦斯?jié)舛冗M行曲線擬合,以數學關系進一步論證這些因素是如何影響瓦斯涌出的。對之前收集整理的紅石巖煤礦12406工作面數據進行統(tǒng)計,利用SPSS相關性分析,發(fā)現煤層厚度和日推進度與絕對瓦斯涌出量顯著相關,底板標高與回風順槽瓦斯?jié)舛蕊@著相關,大氣壓與上隅角瓦斯?jié)舛蕊@著相關;對煤層厚度與日推進度和絕對瓦斯涌出量進行回歸分析,得出這兩個因素與絕對瓦斯涌出量符合三次曲線的變化趨勢,對底板標高和回風順槽瓦斯?jié)舛冗M行回歸分析,得出兩者符合S曲線變化趨勢,對大氣壓和上隅角瓦斯?jié)舛冗M行回歸分析,得出兩者符合S型曲線變化趨勢;對累積進尺和回風順槽瓦斯?jié)舛冗M行分析,得出工作面沒推進25-30米,回風順槽瓦斯?jié)舛染蜁霈F一次峰值;對大氣壓變化量和上隅角瓦斯?jié)舛冗M行分析,得出大氣壓變化的快慢是直接影響上隅角瓦斯?jié)舛茸兓囊蛩亍?br/>[Abstract]:Mine accidents greatly threaten the safety of workers and the property of coal mines. Gas accidents are the most serious and dangerous type of accidents in coal mines. With the increase of mining depth and the acceleration of the speed of working face, many low gas mines also have abnormal gas emission. Therefore, it is of great significance to study the influencing factors of gas emission in low gas mine. Taking 12406 face of Hongshiyan Coal Mine as the research object, this paper analyzes the influence factors of absolute gas emission quantity, upper corner angle and gas concentration in the return air trench, and looks for the most significant factors affecting the gas emission, and combines with regression analysis. The significant factors, absolute gas emission and gas concentration were fitted to the curve, and the mathematical relationship was used to further demonstrate how these factors affect the gas emission. The data collected from 12406 face of Hongshiyan Coal Mine were statistically analyzed. It was found that the thickness of coal seam and the daily advance degree were significantly related to absolute gas emission, and the elevation of floor was significantly related to the gas concentration in the return air trench by using the correlation analysis of the coal seam thickness and the daily advance degree. The atmospheric pressure is significantly related to the gas concentration in the upper corner, and the regression analysis between the coal seam thickness and the daily propulsive degree and the absolute gas emission shows that these two factors and the absolute gas emission are in accordance with the change trend of the cubic curve. Regression analysis of bottom elevation and gas concentration in return air trench shows that both of them are in accordance with the changing trend of S curve, and the atmospheric pressure and gas concentration in upper corner are regressed, and they are in accordance with the changing trend of S type curve. Based on the analysis of the gas concentration in the accumulative ruler and the return air trench, it is concluded that the gas concentration in the return air trench will have a peak value if the working face is not advancing 25-30 meters, and the change of atmospheric pressure and the gas concentration in the upper corner are analyzed. It is concluded that the speed of change of atmospheric pressure is the factor that directly affects the change of gas concentration in upper corner angle.
