煤巷设计高位钻场穿层钻孔测压技术研究

Study on pressure measurement technology of drilling through layers in high-level drilling fields of coal roadway design

为了保障瓦斯压力测定结果的准确性,满足河南省的相关规定要求,在河南芦沟煤矿现有煤巷条件下采取设计高位钻场穿层钻孔测压技术进行煤层瓦斯压力直接测定。通过计算分析对测压结果进行验证,得到本次测压结果真实有效。煤巷设计高位钻场穿层钻孔测压技术在保障测压结果准确性的前提下具有一定优越性。

In order to ensure the accuracy of gas pressure measurement results and meet the relevant requirements of Henan Province,under the conditions of an existing coal roadway in a certain mine in Henan,a design of high-level drilling site through-hole drilling pressure measurement technology was adopted to directly measure the gas pressure of coal seams.The calculation and analysis of the pressure measurement results verified that the current pressure measurement results were true and valid.The pressure measurement technology for drilling through layers in the high-level drilling field of coal roadway design had certain advantages under the premise of accuracy of the pressure measurement.
