摘要:为对小马村矿一5煤层东区开采时通风设计以及瓦斯防治方案制定提供科学依据,通过对煤层瓦斯含量与埋深的回归分析,研究了煤层瓦斯含量分布规律.通过对预测方法特性和适用条件比较,并结合研究矿井的实际,选取了以煤层原始瓦斯含量为基础、能够实现对新(改扩)建矿井进行预测的分源预测法.根据分源预测法计算公式,得到了小马村矿掘进、采煤、采区和矿井最大瓦斯涌出量预测结果,按照矿井瓦斯等级划分标准,判定了矿井瓦斯等级.研究结果对于矿井通风设计和防治瓦斯管理具有重要作用和意义.

The study on the methane storage and discharge rules in Xiaoma coal mine

Abstract:To provide the scientific basis on the mine ventilation design and the gas prevention plans making in mining the one 5 coal bed in the Eastern area of Xiaoma coal mine, gas content distributed laws on the coal bed are studied through the linear analysis on the coal bed gas content and the burial depth.Compared with the property of forecast methods and the suitable conditions, and combined the reality of the mine, plot headstream method, which is on the basis of the coal bed primitive gas content and has been able to realize the forecast in new construct (change, expand) mine, is used in the study.According to the formula of the plot headstream method, the biggest gas discharge quantity forecasting result is obtained when the coal mine will be mined, and subsequent the rank of coal seam methane is determined according to the rank division standard of coal seam methane.The research results have the influential role and the significance on the mine ventilation design and the gas prevention management.
