煤矿钻屑量与解吸指标的测定及误差分析

煤与瓦斯突出已经成为严重的矿山灾害之一,目前其常用的预测方法是钻屑指标法,而在预测过程中钻屑量和瓦斯解吸指标的测定准确度是最关键的,对预测的过程、步骤以及影响预测指标误差的因素进行了分析,并提出了一些在测定过程中应注意的事项和减少误差的措施。

Determination of Drill Cuttings Weight and Gas Desorption Index and Their Error Analysis

Coal and gas outbursts has become one of the serious mine disasters.At present,method of drill cuttings index is commonly used in the prediction of coal and gas outbursts.And the accuracy of drill cuttings and gas desorption index measurements is most key for the prediction of coal and gas outbursts.In this paper,the process,steps of the prediction as well as the factors influencing the errors of predicting indexes are analyzed,the matters to which attention should be paid in the predicting process and the measures of reducing the errors are put forward also.
