一种主动式测压方法介绍及应用

Introduction of an active manometry method and its application

煤层瓦斯压力是预测煤与瓦斯突出的一个极其重要参数,传统的煤层瓦斯压力测定方法由于存在测压时间长、封孔质量差等问题,导致测得的瓦斯压力低于煤层真实瓦斯压力,鉴于此,本文介绍了一种主动式测压方法,该测压方法不仅能快速测定出煤层的瓦斯压力,还能检测出封孔质量的好坏,因此测出的煤层瓦斯压力更具准确性、科学性,不仅能为煤矿生产节约时间,还能为煤矿现场制定防突措施提供理论依据。最后利用该方法对瑞丰煤矿M73煤层的瓦斯压力进行测定,测定结果证实了该测压方法的优越性。

Coal seam gas pressure is an extremely important parameter to predict coal and gas outburst,traditional coal seam gas pressure measurement method exist the problem of long manometry time and poor sealing quality,which lead to the gas pressure measured below the real coal seam gas pressure.As a result,the paper introduces an active manometry method,in which can not only measure coal gas pressure quickly but also to detect the sealing quality is good or not,therefore the coal gas pressure is measured more accurately and scientific,then it can not only save time,but also to provide a theoretical basis for coal mine to formulate outburst prevention measures.at last,using the method to measure the M73 coal seam gas pressure of Ruifeng coal mine,the measurement result confirmed the advantage of the manometry method.
