加菲尔德(Garfield)能源公司是美国第一家在井下使用压气运煤的公司,虽然这种运输系统的能力按一般标准来衡量还不算大,但是,正是这个柯罗拉多的“阳光”矿需要它来增加生产能力和提高生产效率。“阳光”矿由于没有一个良好的运输系统,几年来生产一直受到影响。所以,急需一个高效、经济,且能适应倾角为40度的煤层运输系统,压气运输便能满足这些要求。由Cheyeme、Wyo压气运输公司研制并取得专利的该运输系统,按其实际运输能力计算,其安装费用比运输机低35％,其维护费用也比皮带运输机少。
Garfield Energy is the first company in the United States to use CBM underground. Although the capacity of such a shipping system is not too large to measure by normal standards, it is this Colorado’s “sunshine” Mine needs it to increase productivity and increase production efficiency. Production in the Sunshine mine has been affected for years without a good transport system. Therefore, there is an urgent need for an efficient, economical and capable coal seam transportation system capable of accommodating a dip angle of 40 degrees. Compressed air transportation can meet these requirements. Developed and patented by Cheyeme, Wyo Compressed Transportation, the transportation system, which is 35% less expensive to install than its transporter, is less expensive to maintain than a belt conveyor, according to its actual capacity.
