A few days ago, mining coal seam mining group of anhui province liang huai's conditions CBM extraction demonstration project in the "eleventh five-year plan" results through the national acceptance.

Mining coal seam mining group of liang huai's conditions CBM extraction demonstration project is the national long-term plan for science and technology development (2006 2020). "the sure big oil-gas and CBM development of specific content, huainan mining group by taking the lead, huainan mining group, huaibei mining group, and other units to take major national science and technology project of. This demonstration project has the fruits of the "eleventh five-year plan" period, initially formed with soft, low permeability liang huai's mining area, medium thickness of coal seam mining, under the condition of CBM extraction technology; stereo The low permeability soft coal seam innovative security into the bop extraction and 3 of process; Developed strong outstanding coal seam drill the bop device and so on four equipment and materials.

Mining area in liang huai's mining depth increases year by year, the characteristics of the difficulty of gas control, "1025" during will conduct further soft coal seam coal order extraction recovery of integration of five demonstration task.
