摘 要:为了研究煤矿顶板事故在施工作业中时空发生规律及时空中施工作业相互影响程度,编码分析171份顶板事故调查报告,得出顶板事故时空与施工作业的关系;利用复杂网络理论,提出并构建了基于时空的顶板事故中施工作业耦合网络,采用度数中心性和连边权重分析施工作业与时空的关联强度,采用灰色关联法计算出顶板事故中施工作业的耦合度,提出了煤矿施工作业中预防顶板事故的对策。结果表明:架设支柱与9:00-10:00、维修支架与14:00-15:00、回撤单体液压支柱与采煤工作面、维修支架与回采巷道、锚杆(索)支护作业与回采巷道掘进工作面等在顶板事故中关联较强;维修支架、出煤矸作业、清理煤矸或杂物、架设支柱、架棚作业和锚杆(索)支护作业等在顶板事故中基于时空的平均耦合度较高。In order to study the temporal and spatial occurrence law of coal mine roof accidents in construction operation and the interaction degree of construction operation in the spacetime,171 roof accident investigation reports have been coded and analyzed to obtain the relationship between roof accident spacetime and construction operation.Based on the complex network theory,the construction operation coupling network in roof accidents based on spacetime was proposed and constructed.The degree centrality and edge weight were used to analyze the association strength between construction operation and spacetime,and the coupling degree of construction operation in roof accidents was calculated by grey relation analysis.The countermeasures for preventing roof accidents in coal mine construction were proposed.The results show that the erection of support and 9:00-10:00,maintenance support and 14:00-15:00,recovery of single hydraulic prop and coal mining face,maintenance support and mining roadway,bolt(cable) support and mining roadway heading face are strongly related in roof accidents.The average coupling degree based on spacetime is high for maintenance support,coal gangue removal,coal gangue or debris removal,pillar erection,shed erection and anchor bolt(cable) support in roof accidents.
