摘 要

在矿山生产过程中，某些特定的作业任务，如果其未正确执行，可能造成重大的人员伤亡、财产损失、环境破坏。针对这些情况，本系统建立了安全风险评估管理，使存在危险的作业活动/设备设施能够被评估，员工根据评估结果采取措施，从而有效的降低人为因素造成的损失。

本文介绍了利用Java Web技术开发矿山安全风险评估系统，采用MySQL数据库完成数据库表的设计，实现运用于矿山安全风险评估的风险矩阵评估方法、LEC风险评估方法和FMEA风险评估方法。为实现以上三种方法，本系统结合实际需求，分为风险评价单元划分、危险有害因素辨识、风险矩阵评估、LEC风险评估、FMEA风险评估、风险告知、区域风险评估与统计七个模块，完成如下工作：

1. 完成整个系统功能的需求分析、系统概要设计、详细设计、编码实现及调试、测试工作。设计并实现风险有害因素辨识功能，用户按照岗位、设备、作业活动等开展危险有害因素的辨识，并填写危险有害因素辨识清单，用户可对提交成功后的清单进行删除、归档、查看详细、修改、查询等操作。
2. 设计并实现风险矩阵评估方法、LEC风险评估方法和FMEA风险评估方法的功能，主要涉及添加、删除、归档、查看详细、修改、查询功能。在风险有害因素辨识功能的基础上，用户选择其中一种风险评估方法，按照相应规则评估未被评估过的危险有害因素。对于评估规则，风险矩阵评估法是根据危险源辨识确定的危害的严重程度(S)与危害发生的可能性(L)的乘积确定风险大小；LEC风险评估法是根据危险源辨识确定的危害的可能性(L)、暴露频度(E)与伤害度(C)的乘积确定风险大小；FMEA风险评估法是根据危险源辨识确定的危害的严重度(S)、频度(O)与可探测度(D)的乘积确定风险大小。
3. 设计并实现风险告知功能，包含区域风险告知、重大风险、岗位风险告知三个子模块。主要功能在于标识区域/重大/岗位风险的风险等级、事故类型、措施等。
4. 设计并实现风险评价单元划分模块和区域风险评估与统计模块。风险评价单元划分的功能主要是为用户展现分公司、班组和岗位单元之间所属关系。区域风险评估与统计的主要功能是以统计图的方式向用户展示区域风险等级比。

Abstract

In the mine production process, some specific operation tasks, if they are not carried out correctly, may cause heavy casualties, property losses and environmental damage.In view of these situations, the system establishes safety risk assessment management, so that dangerous operation activities/equipment and facilities can be assessed, and employees can take measures according to the assessment results, so as to effectively reduce the loss caused by human factors.

This paper introduces the use of JavaWeb technology to develop a mine safety risk assessment system, using MySQL database to complete the design of the database table, to realize the use of the mine safety risk assessment risk matrix assessment method, LEC risk assessment method and FMEA risk assessment method.In order to realize the above three methods, the system is divided into seven modules including risk assessment unit division, identification of hazardous and harmful factors, risk matrix assessment, LEC risk assessment, FMEA risk assessment, risk notification, regional risk assessment and statistics according to the actual needs. The following tasks are completed:

1. Complete the requirements analysis, system design, detailed design, coding and debugging, testing of the entire system function.The identification function of risk and harmful factors is designed and realized. Users can carry out the identification of dangerous and harmful factors according to posts, equipment, operation activities, etc., and fill in the identification list of dangerous and harmful factors. Users can delete, file, view, modify and query the list after submission.
2. Design and realize the functions of risk matrix assessment method, LEC risk assessment method and FMEA risk assessment method, mainly involving the functions of adding, deleting, archiving, viewing details, modifying and querying.Based on the identification function of risk and harmful factors, users choose one of the risk assessment methods and evaluate the unassessed dangerous and harmful factors according to the corresponding rules.For the evaluation rules, the risk matrix evaluation method determines the risk size according to the product of the hazard severity (S) determined by hazard source identification and the probability of hazard occurrence (L).The LEC risk assessment method is to determine the risk based on the product of the hazard possibility (L), exposure frequency (E) and damage degree (C) determined by hazard source identification.FMEA risk assessment method is to determine the risk based on the product of the severity (S), frequency (O) and detectability (D) of the hazard identified by hazard source identification.
3. Design and realize the risk notification function, including three sub-modules: regional risk notification, major risk notification and post risk notification.The main function is to identify the risk level, accident type and measures of regional/major/post risks.
4. Design and implement the risk assessment unit division module and the regional risk assessment and statistics module.The function of risk assessment unit division is mainly to show the ownership relationship among branches, teams and post units for users.The main function of regional risk assessment and statistics is to show the regional risk grade ratio to users in the form of statistical graph.
