The drum shearer as recent years shearer representative models , have been applied to the majority of large - scale coal production enterprises is the core of modern high-yielding and efficient mechanized mining face equipment , its reliability has become a measure of the shearer performance an important indicator of the reliability of the shearer not only with the shearer design , manufacture , also with shearer transport , storage , installation, use , maintenance and other areas have been closely linked , so from shearer an important issue in the design to shearer reliability engineering to build a system scrapped the entire process of life , thus shearer reliability study is an extremely significant issue , but also to adapt to the modern coal production . This topic is cross interdisciplinary cooperation with the School of Economics and Management , the thesis to the typical life-cycle theory based on the full life-cycle theory of the drum shearer drum shearer from a management point of full life-cycle reliability covers many aspects of equipment management , quality management , the issues involved in the design , inherent reliability of the manufacturing stage management and logistics , installation, use , maintenance stage reliability management , but focused on the shearer use reliability studies in phases , different levels of reliability management were discussed in detail , the shearer use statistical analysis by several trips Shendong Mining research data , the shearer life of the common faults and failure rate analysis , and application of fuzzy reliability theory and multi- index comprehensive evaluation method the comprehensive overhaul shearer reliability evaluation model , and finally in the the shearer reliability management system developed using the PHP programming language PHP5, MySQL, Apache software environment ( the RMS system) , RMS system function framework structures and basic database development . The ultimate purpose of the subject is the inherent reliability of the reliability of the shearer full life cycle management to improve Shearer , effectively maintain Shearer reliability , reduce shearer failure rate , extend the shearer life , produce more more economic value .
