在总结胶囊-黏液封孔测压设备在使用过程中常发生的各种事故的基础上,利用事故树分析法推导分析了导致事故发生的各种可能原因及这些原因之间的关系。然后通过分析和计算找到了防止事故发生的最佳途径并得出了防止胶囊-黏液封孔测压设备测定煤层瓦斯压力过程中出现事故的注意事项。
On the basis of summarizing various accidents that occur frequently in the capsule - mucus sealing and pressure measuring equipment during the using process, the causes of accidents and the relationships among these causes are deduced and analyzed by using the method of accident tree analysis. Then the best way to prevent accidents is found through the analysis and calculation, and the precautions to prevent the accidents in the determination of gas pressure in the coal seam by the capsule-mucus sealing and pressure measuring equipment are obtained.
