矿山开采后期的特点不仅仅是采矿量减少，而且采矿条件在不断发生变化，往往是日益恶化。不采取避免采矿量降低和采矿条件改变引起的不良后果，就会导致企业生产指标和经济指标不断恶化。为了防止这个过程的发生，必须在考虑到矿床开采后期特点的情况下完善采矿工艺及生产管理
The latter part of the mine is characterized by more than just a reduction in the amount of mining and the constantly changing mining conditions, which are often deteriorating. Failure to avoid the adverse consequences of reduced mining volumes and altered mining conditions will result in deteriorating corporate production and economic indicators. In order to prevent the occurrence of this process, we must improve the mining process and production management, taking into account the characteristics of the latter part of the deposit
