煤层瓦斯压力测定的新型注浆封孔技术研究
首发时间:2010-01-14
摘要:我国绝大多数煤矿是高瓦斯或突出矿井,瓦斯事故是制约煤矿安全生产的主要因素。瓦斯压力是瓦斯在煤层中流动的动力,是计算煤层瓦斯含量多少以及瓦斯动力现象潜能大小的主要参数。在煤与瓦斯突出的发展、发生过程中,瓦斯压力起着重大作用。煤层瓦斯压力的准确测定,对于煤矿安全生产具有非常重大的意义。煤层瓦斯压力测定的新型注浆封孔技术,克服了不同测压法存在的缺点,其两端封闭的注浆室能很好地密封钻孔不漏气。其操作步骤简单,成本低,部分材料可以回收利用,准确可靠,具有广泛的推广应用价值。

The coal bed gas pressure determination new note thick liquid seals the hole engineering research
Abstract:Our country overwhelming majority coal mine is the high gas or the prominent mine pit,The gas accident is restricts the coal mine safety production the primary factor. The gas pressure is the gas the power which flows in the coal bed, Is calculates coal bed gas content how many as well as the gas power phenomenon potential size main parameter. In the coal and the gas prominent development, have in the process, the gas pressure is playing the significant role.Coal bed gas pressure accurate determination,Has the extremely significant significance regarding the coal mine safety production.The coal bed gas pressure determination new note thick liquid seals the hole technology,Has overcome the different manometric method existence shortcoming, its both sides seal note thick liquid room can seal the drill hole to be airtight well.Its sequence of operation is simple, the cost is low, the partial materials may recycle the use, accurate reliable, has the widespread promotion application value.
Keywords: Importance Gas pressure determination The new note thick liquid seals the hole technology Both sides seal note thick liquid room Airtight
