摘要
从典型的阳泉矿区南庄煤矿入手,分析利用现行分源瓦斯预测方法预测量远低于实际瓦斯涌出量的问题,提出南庄煤矿12号煤层上邻近的石灰岩K2,K3,K4的瓦斯涌出,使得12号煤层上邻近层实际瓦斯涌出量远大于用传统分源预测法计算出的瓦斯涌出量的原因;采用矿山统计法和分源预测方法相结合准确计算出南庄煤矿12号煤层上邻近的瓦斯涌出量.提出阳泉矿区上邻近层与本煤层瓦斯涌出量的比例.
Sarting from the coal mine of Yangquan mining area Nanzhuang typical analysis, forecasting method using the current source gas is much lower than the amount of actual gas emission, the Nanzhuang coal mine No. 12 coal seam gas near K2, K3, K4 of the limestone that gush, No. 12 coal seam in upper layer of actual gas emission is much larger than the amount calculated by gas the tradition- al source prediction method of gas emission; Using methods which combine mine statistical and source prediction accurately calculates Nanzhuang coal mine 12 coal seam near the gas emission The proportion of the gas emission from the coal seam and the upper adjacent layer in Yangquan mining area are put forward.
