PDCA循环法是全面质量管理的一种方法,它分计划(Plan)、实施(Do)、检查(Check)、处理(Action)四个阶段。这四个阶段头尾衔接,反复循环,可用图1表示。在井区通风防尘中,运用PDCA循环法,对于提高粉尘浓度合格率,减少矽尘危 PDCA cycle method is a method of total quality management. It is divided into four phases: Plan, Do, Check and Action. These four stages head and tail convergence, repeated cycles, available Figure 1 said. In the well ventilation and dust prevention, the use of PDCA cycle method, for improving the passing rate of dust concentration and reduce the risk of silica dust
