摘要: 目前煤矿瓦斯治理管理关键环节仍需要人工监督，瓦斯治理措施达不到“质量可靠”和“过程可溯”，且瓦斯治理管理模式落后造成职能重叠、流程不畅、数据共享程度低。针对上述问题，基于工作流技术，从全局管理的角度开展了煤矿瓦斯治理动态工作流构建方法研究。首先，对采掘工作面和揭煤工作面瓦斯治理的工作流程、约束条件和实施过程进行了分析，将瓦斯治理流程划分为测试和措施2类环节，并具体化为技术文档和报告单审批、钻孔施工、取制样、瓦斯参数测定、抽采及其参数检测等5类工作。然后，将上述后4类工作重构，并进一步拆分为25个基本工作单元，利用Petri Nets对基本工作单元进行组合，用于建立不同跨部门瓦斯治理复杂业务工作流程，基于瓦斯治理工作流程图建立工作面瓦斯治理执行进度表示方法，采用主动和自动相结合的策略对工作流进行任务分配，使用描述文件动态生成和配置工作流网络满足对瓦斯治理动态工作流建模的要求。最后，基于Flowable工作流引擎进行瓦斯治理动态工作流功能的开发和应用。结果表明，动态工作流的构建可以使瓦斯治理业务流程化，有利于提升瓦斯治理协同执行效率，实现数据的快速流转、追踪和共享，便于监控瓦斯治理工作的整体运行和优化，提高煤矿瓦斯治理决策能力，创新煤矿瓦斯治理管理模式。Abstract: At present, the key links of coal mine gas control management still need manual supervision. The gas control measures can not achieve "reliable quality" and "process traceability". The backward gas control management mode results in overlapping functions, poor process and low degree of data sharing. In view of the above problems, based on workflow technology, from the perspective of global management, the dynamic workflow construction method of coal mine gas control is studied. Firstly, the workflow, constraint conditions and implementation process of gas control in the minging face and coal uncovering working face are analyzed. The links of gas control flow is divided into two types: test and measure. It is specifically divided into five types of work, including approval of technical documents and reports, drilling construction, sampling, gas parameter measurement, and gas extraction and parameter detection. Secondly, the method reconstructs the last four types of work and further divides the work into 25 basic work units. The method uses Petri Nets to combine basic work units to establish different cross-departmental gas control complex business workflow. Based on the gas control workflow chart, a representation method for the implementation progress of gas control in the working face is established. The method uses the strategy of combining initiative and automation to assign task of the workflow. The method uses description files to dynamically generate and configure workflow networks to meet the requirements of dynamic workflow modeling for gas control. Finally, based on the Flowable workflow engine, the dynamic workflow function of gas control is developed and applied. The results show that the construction of dynamic workflow can make the gas control business process. It is conducive to improving the efficiency of gas control collaborative execution, realizing the rapid flow, tracking and sharing of data. It is conducive to monitoring the overall operation and optimization of gas control work, improving the decision-making capability of coal mine gas control, and innovating the management mode of coal mine gas control.
