在生产发展中,矿井瓦斯涌出量大大增加,并伴随产生煤和瓦斯突出.进行新区瓦斯预测,把预防瓦斯工作做在瓦斯未发生之前,就非常必要.以往预测新区瓦斯涌出量,是把瓦斯与开采深度看成正比关系进行的.最近,又有人提出在一定深度处瓦斯将达到极限值.以上看法只适合于煤层地质条件完全相同的地区.实际生产中经常碰上复杂的煤层地质变化,这种变化对瓦斯涌出量影响很大.因此,应该把瓦斯涌出量在空间和时间上的多变性,看成是各种因素综合影响的结果.本文介绍在生产中,应用统计方法找出瓦斯涌出量与各影响因素的定性定量关系,根据这种关系和新区条件,进行瓦斯预测.
In the development of production, gas emission from mines is greatly increased, accompanied by the generation of coal and gas outburst.It is necessary to carry out gas prediction in new area and make gas prevention work before gas does not occur.Previously, gas emission in new area is predicted to be The gas and the mining depth as a proportional relationship.Recently, it was suggested at a certain depth of gas will reach the limit value.The above view is only suitable for the same geological conditions in the coal seam.In practice, production often encounter complex seam geology Change, this change has a great impact on the amount of gas emission.Therefore, gas emission should be in space and time variability as a result of a combination of various factors.This article describes the production, the application of statistics Method to find out the quantitative relationship between gas emission and various influencing factors. According to this relationship and the conditions in the new area, gas forecasting is carried out.
