本文讲述乌克兰顿巴斯矿区的煤层气抽放和利用,分析了综合开发和利用瓦斯的新方案,并选择伯克罗夫斯科矿务局做为实施方案的地点,该矿务局是乌克兰最大矿务局,年产800万t煤。实践证明从地面抽放瓦斯的优越性,每年要建设约50口抽放井的方法,顿涅茨克钢铁公司选用Ultra Single 150型(加拿大)钻机,进行钻孔。阐述这种钻机结构和使用方法,速度达到约60m/h,每昼夜速度达到620m,比原有钻机提高速度2～3倍,使用多晶体PDC型钻头,一个钻头可钻深7000多m。在煤层气利用方面,采用热电联产气体活塞式发电站,可供矿务局所需电量的54%,效益好,可推广。
This paper describes CBM drainage and utilization in the Donbass mine in Ukraine, analyzes new options for the comprehensive development and utilization of gas, and selects the Berkrovsk Mining Bureau as the site for implementation of the program, which is Ukraine The largest mining bureau, with an annual output of 8 million tons of coal. Practice has proved that the superiority of gas drainage from the ground, every year to build about 50 pumping wells, Donetsk Iron and Steel Company use Ultra Single 150 (Canada) rig, drilling. Describe the structure and use of this rig structure, speed of about 60m / h, every day and night speed of 620m, than the original rig to increase the speed of 2 to 3 times, the use of PDC polycrystalline bit, a drill can drill more than 7000 m deep. In CBM utilization, the use of cogeneration gas piston power station, available for 54% of the electricity required by the Bureau of Mines, effective and can be promoted.
