钱家营矿是一座设计能力年产原煤400万吨的特大型矿井,自1988年投产后,亏损逐年增长。1991年亏损接近1.1亿元,大量亏损给新井的经营工作造成巨大压力。新井亏损严重,除煤炭价格与价值背离外,主要为新井自身特点所决定。突出表现在以下几个方面: 1.达产前产量低,吨煤成本高。新井从投产到达产,需要经过一定年限。在这个期间产量低、成本高、亏损大。钱家营矿1989～1991年原煤产量分别为设计能力的40%、50%和 Qianjiaying Mine is a large-scale mine capable of designing an annual capacity of 4 million tons of raw coal. Since its operation in 1988, the loss has been increasing year by year. In 1991, the loss hit nearly 110 million yuan, causing huge losses to the management of Xinjing. New wells suffered serious losses, with the exception of coal prices and the value of departure, mainly for the new wells its own characteristics. Outstanding performance in the following areas: 1. Up to pre-production low yield, high cost per ton of coal. New wells from production to production, the need to go through a certain number of years. During this period, low output, high cost, large loss. Qianjiaying Mine 1989 ~ 1991 raw coal production capacity of 40%, 50% and design capacity respectively
