三个煤量是反映矿井采掘状况的重要依据,分别反映矿井生产准备阶段完成的程度和效果。一个产量和开拓方式既定的矿井,其三量可采期之间,一般保持一定的比例协调关系。矿井实际统计资料说明,严格按《三量规定》计算矿井三量,并根据各种矿井实际算出三量合理可采期是能反映采掘比例关系的。要以矿井实际
The three coal mines are an important basis for reflecting the status of coal mining and reflect the extent and effectiveness of completion of the mine production preparation respectively. A production and development methods established mine, the volume between the three recoverable period, generally maintain a certain proportion of coordination. According to the actual statistics of mines, the three mines are calculated strictly in accordance with the “Three-volume Rules” and the three recoverable mines can be calculated according to the actual mines. To mine in actual
