羊渠河矿二井1959年投产。由于井型设计较小,对矿井地质条件及沼气涌出量估计不足,矿井各个生产环节显得薄弱而不配套。尤其是采区巷道布置上的不合理,致使生产过程中沼气经常超限。为了解决这个问题,在巷道布置上做了技术改造,不仅适应了生产需要,而且使井口年设计能力从45万吨提高到90万吨。 一、井田地质条件及沼气涌出状况 羊二井田西与五矿接壤,处在地垒构造的地台上,四周均为断裂下降盘。井田内地层大致呈板状单斜,走向东北,倾向
Yangqu River mine two wells put into operation in 1959. Due to the small well design, insufficient estimation of mine geological conditions and methane emission, each production link in the mine is weak and not suitable. In particular, the layout of the roadway in the mining area is unreasonable, resulting in frequent over-limit of biogas in the production process. In order to solve this problem, technical reconstruction has been made in the layout of the roadway, not only to meet the production needs, but also to improve the designed annual wellhead capacity from 450,000 tons to 900,000 tons.
