作为通风部一员时刻把“一通三防〞工作作为矿井平安的重中之重，时刻围绕通风平安、瓦斯抽放、监测监控及瓦斯突出工作为工作重点，管平安就要懂平安，一个平安工作者，要做的不仅仅是把自己的平安工作搞好，要有责任及义务让每一个人从内心认识到平安责任的重大，讲平安事故吸取平安经验，从根本上认识到灾害对自己的伤害，懂得灾害带来的后果，才能从本身抓起平安，只有意识上的平安才能认识到平安的重要性，只有意识上的平安才能认识到实际操作中不平安因素。

Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured
