瓦斯爆炸一直是中国煤矿的主要事故类型之一，可靠的应急救援过程是将事故损失降至最低的关键保证之一。流程挖掘作为一门发现流程瓶颈和定位偏差的新兴学科，近年来被广泛应用于各种业务流程的改进。然而，据我们所知，将其应用于煤矿应急救援领域的研究还很少。本研究将过程挖掘技术应用于煤矿瓦斯爆炸事故应急救援领域。选取2006-2014年下半年我国煤矿发生的50起重大重大瓦斯爆炸事故作为录井数据。通过流程挖掘，分析了流程视角、案例视角、直升机视角、组织维度和绩效视角。从控制流的角度，利用PROM中的归纳矿工提取了应急救援模型，并与实际模型进行了一致性检验和比较，验证了本文工作的有效性。研究还显示，案例的平均时长为23.72个事件，60%的案例处于平均时长以下；56%的瓦斯爆炸事故应急救援过程持续时间不到两天；应急救援指挥部、军士长和医务人员在救援社会网络中的中心度最高；与事故地点、煤矿区域和煤矿所有权因素相比，事故等级对救援绩效的影响更大。
Gas explosion has always been one of the major accident types in the coal mines of China, and reliable emergency rescue process is one of the key guarantees to minimize accident losses. As an emerging discipline to discover bottlenecks and position deviations of processes, process mining is widely used to improve various business processes in recent years. Nevertheless, scarcely does any research apply it to the field of coal mine emergency rescue to our knowledge. In this study, we apply the technique of process mining to domain of gas explosion accident emergency rescue in coal mines. 50 considerable and major gas explosion accidents, which occurred from the second half of 2006-2014 in Chinese coal mines, are selected as log data. The aspects of control-flow perspective, case perspective, helicopter view, organizational dimension and performance perspective are analyzed by process mining. In terms of control-flow perspective, the emergency rescue model is extracted by the inductive miner in ProM, correspondingly, conformance checking and comparison with real-life model have shown the validity of our work. Research also shows that the average length of cases is 23.72 events, and 60% of the cases are under the average length; 56% of the gas explosion accident emergency rescue processes last less than two days; emergency rescue headquarters, barmaster and medical staff share the highest centrality in social network of rescue; the rescue performance is more affected by accident grade, compared with the factors of accident site, region of coal mine and coal mine ownership.
