While driving only two places at a time is efficient for continous mining,conventional mining with five unit operations requires driving at least one working place for each operating machine,with a total of 7 to 10 working place desirable for greater efficiency.Because safety conditions override production considerations,as many as 16 working place may be driven in parallel,primarily to provide sufficient ventilation and haulage capabilities.Thus,usually a minimum of five main entries will be driven in opening a drift mine into a coal outcrop,as is shoun in Fig.8.2

对于继续采矿来说,一次性打入两处是有效率的.通常在采矿中,每个机器打入至少一次需要5次操作.最理想最高效的是将打入总次数控制在7-10次.因为在确保安全的前提下,不考虑产品,16处平行打入,能够提供足够的通风以及搬运容量.因此最少5个主要入口常应用于将开放式矿井开采为裸矿,如数据8.2所示,
