摘要
井下人员定位系统是矿井安全生产和应急救灾过程中不可缺少的设备,因此,探讨基于ZigBee技术的井下人员定位系统关键技术具有重要的现实意义。文章根据矿井实际需求,从本质安全型电源设计、数据库软件选择与设计、井下人员精确定位等关键技术进行了探讨和分析,对井下人员定位系统功能的完善有一定的指导意义和参考价值。
By collecting the datum of support working resistances and roadway section during the end mining of №22107 working face of Cuncaota coal mine,the paper analyzed the change of retracement channel during the holing through of working face,achieved the distribution of advancing support pressure and the stress concentration combined with numerical simulation and summarized the experience of holing through of end mining face. The result can provide reference for holing through and equipments retracement of fully mechanized mining face.
