一、停送电安全保障文化的产生背景1.不断提升的矿井生产能力城郊选煤厂原设计年处理能力为240万吨。自投产以来,为适应城郊矿产能的不断提升,城郊选煤厂也在不停地进行扩能改造,现年处理能力已达500万吨。即使这样,受厂房空间及厂址占地面积的影响,城郊选煤厂处理能力已达到极限,必要时只有通过延长设备运转时间、压缩设备检修时间以保证矿井生产,曾经创造过连续六天六夜不停机检修的记录。如此长时间的连续运转,给机电设备维护、抢修期间的人员安全带来了诸多不稳定因素!2.重介质洗煤工艺的特殊性
First, to stop sending electricity security culture Background 1. Increasing mine capacity Suburb coal preparation plant designed to handle the original annual capacity of 2.4 million tons. Since put into production, in order to meet the continuous upgrading of suburban mineral resources, suburban coal preparation plant is also ongoing expansion of capacity expansion, the processing capacity has reached 5 million tons. Even so, affected by the space of the workshop and the site area, the treatment capacity of the coal preparation plant in the suburbs has reached the limit. Only when it is necessary to prolong the running time of the equipment and compress the equipment overhaul time to ensure the mine production have been created for six days and six nights Non-stop maintenance records. Such a long period of continuous operation, to mechanical and electrical equipment maintenance, personnel safety during the repair brought a lot of instability! 2. Dense medium coal washing process is special
