坑木是煤矿生产建设的重要物资,全国煤矿每年消耗坑木上千万立方米。但这些坑木不构成产品实体,做好井下坑木回收和综合利用工作,对节约木材,减少浪费,提高经济效益有重要的现实意义和战略意义。湖南省煤炭系统从1978年开始与冷水滩造纸厂互相协作,把煤矿井下回收出来而自己又不能利用的短坑木集中起来,交纸厂造纸。截止1989年上半年止,煤矿共交冷水滩纸厂的坑木42,
Keng Mu is an important material for the production and construction of coal mines. National coal mines consume tens of millions of cubic meters of pits every year. However, these pits do not constitute a product entity, and do a good job of recovering and comprehensive utilization of underground pit pits.
