总进尺:它是反映回采与掘进比例关系的指标,是保证煤矿持续正常生产的重要条件。掘进是为了矿井正常生产的需要,在煤层或岩层中,开凿各种形状、不同断面、纵横交错的井、巷、峒室工作,称为掘进。其掘进的井巷长度为进尺。总进尺,包括生产掘进进尺、开拓延深掘进进尺、老矿挖潜工程进尺以及不停产进行改、扩建工程等掘进进尺。全员效率:这一指标反映生产矿井生产人员,在一定时间内实物劳动生产率的水平,因而它是重要的经济技术指标。它包括原煤生产过程中直接从事原煤生产活动和为原煤生产服
Total footage: It is an index that reflects the relationship between recovery and excavation, and is an important condition for ensuring the continuous normal production of coal mines. Digging is for the normal production of mines. In coal seams or rock formations, the work of drilling wells, alleys, and chambers with various shapes, sections, and criss-crosses is called excavation. The length of the tunnel to be driven is a footage. The total footage, including the production of drilling footage, the development of deepening and digging footage, the footage of old mines for digging submersibles, and the progress of diversions such as renovations and expansions without stopping production. Total staff efficiency: This indicator reflects the level of physical labor productivity of the production mine production personnel within a certain period of time. Therefore, it is an important economic and technical indicator. It includes raw coal production directly in raw coal production and raw coal production.
