摘要: 为了确定察哈素煤矿回风隅角CO浓度变化的主要影响因素,以察哈素煤矿31209和31313综采工作面为例,从开采技术条件入手,采用灰色系统关联度的分析方法定量分析各开采技术条件对回风隅角CO浓度的影响程度。结果表明:影响回风隅角CO浓度的主要因素为工作面配风量,其关联度在2个工作面分别为0.86和0.87;另1个主要影响因素为地面大气压,其关联度在2个工作面分别为0.82和0.86;日推进量和回采率影响较小,工作面漏风量对回风隅角CO浓度的影响不明显。Abstract: In order to determine the main influencing factors of the CO concentration change at the return air corner in Chahasu Coal Mine, taking 31209 fully mechanized mining face and 31313 fully mechanized mining face of Chahasu Coal Mine as examples, the influence degree of each mining technical condition on the CO concentration at the return air corner was quantitatively analyzed by the analysis method of grey system correlation degree from the mining technical condition. The results show that the main factor affecting the CO concentration at the return air corner is the air volume of the working face, and the correlation degree is 0.86 and 0.87 respectively. The other major factor is the surface atmospheric pressure, and its correlation degree is 0.82 and 0.86 respectively. The influence of daily advance rate and recovery rate is small, and the influence of air leakage rate on CO concentration in return air corner is not obvious.
