地下矿山更重视空间与班次 Underground mining: space and shifts
地下作业应重点核对巷道空间、孔位方向、通风、供气距离、搬运条件和班次节奏。 Check roadway space, hole direction, ventilation, air-supply distance, handling and shift requirements.
隧道施工要结合断面和孔网 Tunneling: cross-section and hole pattern
隧道选型需结合断面、炮孔布置、计划进尺、作业平台和多台设备同时工作的供气条件。 Consider tunnel cross-section, blast-hole layout, planned advance, work platform and simultaneous air demand.
采石与石材工况要区分作业方式 Quarrying and stone work: choose the working method
采石和石材钻孔需确认材料、孔径、孔深、钻孔方向和工作节奏，并区分气腿式与手持式需求。 Confirm material, hole diameter/depth, drilling direction and work cycle, and distinguish air-leg from handheld requirements.
