新建矿井,地面没有矿区控制网,为了保证主副斜井的精确贯通,两头对向掘进,形成井筒贯通方案。为将误差降低到最低程度,运用全球定位系统（GPS）进行矿区平面控制,建立地面近井控制网。选用GPS建网方案,井筒位置及网形布设。%The ground of new mines without mining area control network, in order to guarantee the precise transfixion main auxiliary slope, we take measures to form wellbore transfixion scheme by two toward the tunneling. Error can be reduced to a minimum level adopting global positioning system （GPS） in mining area control and establishment of ground nearly well control network. GPS arrangement plan, shaft location and net form layont are chosen.
