盘江矿区具有丰富的煤层气资源,据初步计算,煤层气储量约1.243×10~(11)m~3。矿区内有8座瓦斯抽放站,抽放能力达1×10~8m~3/a以上,每年因开采排入大气的纯瓦斯1～1.7×10~(11)m~3,为在以用促抽、保障矿井安全生产的同时达到提高资源利用率和保护环境的目的,开发利用盘江矿区的煤层气已显得十分必要,并可取得较好的经济效益。
The Panjiang mining area has rich CBM resources. According to preliminary calculations, the CBM reserves are about 1.243 × 10 ~ (11) m ~ 3. There are 8 gas drainage stations in the mining area with drainage capacity of 1 × 10 ~ 8m ~ 3 / a or above. The annual discharge of pure methane into the atmosphere is 1 ~ 1.7 × 10 ~ (11) m ~ 3, It has become necessary to develop and utilize CBM in Panjiang Mining Area with promoting pumping and ensuring safe production of coal mines, and at the same time achieving the goal of improving resource utilization and environmental protection, and achieving better economic benefits.
