| 摘 要： | 我国煤层气资源非常丰富。在煤矿区，煤层气(瓦斯)开发具有增加洁净能源供给、提高煤矿安全生产保障能力、减少温室气体排放等多重效益。地面钻井开发与井下钻孔抽采是煤矿区煤层气(瓦斯)开发的基本途径，同时也是煤矿区应急救援的主要手段。本文介绍了煤矿区地面煤层气开发新技术装备，大直径钻孔施工技术与装备及井下中硬、松软煤层和岩层瓦斯抽采钻孔成孔技术与装备。在此基础上分析了在新形势下煤矿区煤层气（瓦斯）抽采钻孔成孔技术和装备发展需求，为我国煤矿区煤层气（瓦斯）钻孔成孔提供借鉴。

| Abstract: | Coal bed methane resources are very rich in china. In the coal mine area, the development of coal bed methane (gas) can increase the supply of clean energy, improve the ability of coal mine safety production, and reduce the emission of greenhouse gas and so on. Surface and downhole drilling are the basic ways to develop coalbed methane (gas) and the main means of the emergency rescue in coal mine area. This paper introduces new technical equipment of coalbed methane exploiting on ground surface, large diameter drilling construction technology and equipment as well as boring technology and equipment for gas drainage in medium hard and soft coal seams as well as rock stratum. Based on the above, the analysis is made on the development demands on technology and equipment of coalbed methane (gas) drainage drilling in new situation. |
