为了保证煤矿持续、稳定地生产,必须正确处理好采掘关系的平衡和合理调整,实际上就是平衡采掘之间错综复杂的比例关系。定期反映采掘动态,及时调整采掘比例关系,正确衡量开拓掘进工程效果,定期予告矿井的水平、采区、工作面三大接替的正常与紧张程度,就是制定三个煤量及其合理可采期规定的目的。
In order to ensure the sustained and steady production of coal mines, the balance and rational adjustment of the mining relations must be properly handled. In fact, the complicated and proportional relationship between the balance mining should be properly handled. Regularly reflect the mining dynamics, timely adjustment of the proportion of mining relations, the right to measure the effect of pioneering excavation project, regularly to the level of the mine, mining area, face three major succession and normality is the development of three coal and its reasonable recoverable period Prescribed purpose.
