[Abstract]:Mine production equipment is the necessary guarantee of mine production capacity, the use of equipment will lead to equipment failure. According to the system safety theory, the fault state of the equipment can not be completely eliminated in production and use. The failure rate should be controlled to an acceptable level, and the equipment failure should be reduced by improving the technical and management effectiveness of the equipment, that is, reliability. Taking the specific type of perforated equipment in opencast mine as the sample, taking the use of these equipment and the data of maintenance record as the material, and using the method of reliability analysis, the influencing factors and improving measures of the fault control of perforation equipment are qualitatively analyzed. Quantitative analysis. The research contents include the statistical analysis of reliability characteristic quantity of perforated equipment, the establishment of reliability stochastic simulation model, the verification of reliability improvement index and so on. Under the premise of accord with the characteristic quantity of equipment reliability, the main factors influencing the available time of the equipment are analyzed, and the result of the change of the equipment availability caused by the change of each factor is analyzed through the random simulation model test. Identify the main ways to improve the utilization of equipment. In this paper, FMECA-FTA analysis is used to select the maintenance or replacement strategy of important equipment units, to control the failure rate of the equipment within an acceptable range, and to improve the equipment production capacity. The research results of this paper are as follows: 1) the KQ-200 drilling rig has completed the ruler in a specified time, and the probability of the running time and the waiting time is normal distribution, while the maintenance time is long, The probability of the waiting time is negative exponential distribution. (2) the random simulation model of equipment reliability analysis is established according to the respective characteristic quantity of drill rig and verified. The simulation results show that the comprehensive management measures are the most effective to improve the utilization rate of the equipment, and the simulation results show that the failure rate control scheme of the perforating equipment can be used as a reference for the improvement of the equipment use and maintenance work. The annual working days of each rig can be increased by 5 / 9 respectively: shortening the waiting time also has obvious effect on improving the working efficiency of each rig. The failure type, cause and influence index of KQ-200 drilling rig are obtained by FMECA and FTA analysis. This paper determines the most harmful component structure of submersible drilling rig and the failure rate of drilling rig determined by the failure rate of components and devices, and puts forward the rectification measures. 5) using reliability analysis method to deal with the equipment failure events that occur in random way. The method of stochastic simulation can be used to improve the management of mine equipment and increase the production capacity of equipment.
