The statistical analysis results on methane release in coal faces in Kuzbass are presented. The parabolic curves of methane release have maximums as regard to feed velocity and productivity of shearer. Methane release from broken coal is an inverse proportional function of linear hyperbolic dependence and has maximum as regard to feed velocity and productivity of shearer. The analysis of the found methane release from broken coal shows that methane release reduces as a quadratic dependence with decreasing drum rotation speed and number of picks per cutting line, and increases also as a quadratic dependence with growing thickness of coal seam and shearer web width.

库兹巴斯高产工作面甲烷释放量统计分析

给出了库兹巴斯煤工作面甲烷释放的统计分析结果。甲烷释放的抛物线曲线在采煤机的进料速度和生产率方面具有最大值。破碎煤中的甲烷释放是线性双曲线相关性的反比函数，并且对于采煤机的进料速度和生产率具有最大值。对破碎煤中发现的甲烷释放量的分析表明，甲烷释放量随滚筒转速和每条切割线的截齿数的降低呈二次方关系降低，并且随着煤层厚度和采煤机腹板宽度的增加呈二次方关系增加。
