我矿属缓倾斜多层薄矿体。自1953年以来,一直沿用长壁法单层分采,二十年来先后进行了二十多种长壁法变型方案的试验,也积累了一定的生产经验。但长期生产实践证明,长壁法存在一些严重缺点,如采场易冒顶,作业不够安全,坑木消耗大,采矿强度不高,工效低,巷道保留时间长,劳动强度大等,使矿山至今未能达到设计规模。经过无产阶级文化大革命锻练的我坑广大革命职工,在党的领导下,在北京矿冶研究院的帮助下,坚持以党的基本路线为纲,贯彻“鞍钢宪法”,打破洋框框,为寻求一种安全、低耗、高强度的采矿方法进行了大胆地试验。在我矿有
My mine is gently inclined multi-thin ore body. Since 1953, it has been used for long-wall single-layer separation and mining. In the past 20 years, it has carried out more than 20 kinds of experiments on long wall deformation programs and also accumulated some production experience. However, long-term production practices have proved that there are some serious shortcomings in the long wall method such as easy roof fall, insufficient safety of work, expensive pit mining, low mining intensity, low work efficiency, long laneway retention time and labor intensity, Failed to reach the design scale. Under the leadership of the party and with the help of the Beijing Mining and Metallurgy Research Institute, I insisted on following the basic line of the Party as the key link, implementing the “Angang Constitution”, breaking the gap between the Seeking a safe, low-cost, high-intensity mining method has been boldly tested. I have mine
