当前，国有煤矿都面临市场问题，许多国有煤矿陷入困境，造成这种局面的外部根源是计划经济体制下签订的供煤协议的失效和大量寄生于国有煤矿的小煤窑的不公平竞争；而内部根源则是国有煤矿缺乏对市场的应变能力。露天煤矿较之矿井有调节空间大和生产弹性大等优势，如能充分利用这些优势，并在规模确定、设备能力、洪峰削减、土地征用和人员配置等方面引入一些新的观念，就能显著提高露天煤矿对市场的应变能力，从而改善露天煤矿的经济效益 Currently, state-owned coal mines are facing market problems and many state-owned coal mines are in trouble. The external causes of this situation are the failure of the coal supply agreement signed under the planned economy and the unfair competition caused by the large number of small coal mines that parasitize the state-owned mines. Internally The root cause is the lack of adaptability to the market in state-owned coal mines. Opencast coal mines have the advantages of large adjustment space and greater production flexibility than those of mines. If we can make full use of these advantages and introduce some new concepts in scale determination, equipment capacity, peak reduction, land acquisition and staffing, etc., we can significantly improve Surface coal mine on the market resilience, so as to improve the economic efficiency of open-pit coal mines
