摘要
在爆破作业中,安全管理发挥着至关重要的作用,爆破安全与“钻孔、爆破、采装、运输、排土”等工艺流程密切相关,工序之间相互作用显著。然而,由于现有爆破安全数据来源多样、结构复杂,缺乏系统化集成,导致现场作业人员在面对复杂工况时难以准确获取关键安全知识,给安全管理带来了挑战。因此将基于BERT-BiLSTM-CRF的命名实体识别方法应用于爆破安全管理领域。首先采用BERT预训练模型获取动态词向量,其次采用BiLSTM-CRF进行实体最佳标签序列标注,构建了涵盖7类实体和9类关系的知识图谱,并利用开源图数据库系统Neo4j存储知识图谱数据。结果表明:模型所有实体类型的F 1值均在60%以上,证明该模型较传统模型实体识别提取精度显著提高。并基于知识图谱模型开发了露天煤矿爆破工艺安全管理知识问答系统,完成领域知识查询及各类爆破工艺与安全标准的迅速匹配。通过问答系统的支持,现场工程师能够在复杂的爆破安全管理中迅速做出科学决策。
Safety management plays a vital role in blasting operations,and blasting safety is closely related to the processes of drilling,blasting,loading,transportation,and dumping,with significant interactions among these procedures.However,due to the diverse sources and complex structure of current blasting safety data,the lack of systematic integration poses challenges for on-site personnel to accurately acquire critical safety knowledge under complex working conditions.To address this issue,this study applies a BERT-BiLSTM-CRF-based method for entity recognition in the field of blasting safety management.The BERT pre-trained model is first used to obtain dynamic word embeddings,followed by optimal label sequence tagging using the BiLSTM-CRF model.A knowledge graph covering seven entity types and nine relationship types is constructed and stored using the open-source Neo4j graph database system.Experimental results show that the F 1-score for all entity types exceeds 60%,demonstrating that the proposed model significantly improves entity recognition accuracy compared to traditional models.Based on this,a knowledge graph-based Q&A system for blasting process safety management in open-pit coal mines is developed,enabling rapid querying of domain knowledge and efficient matching of various blasting processes with safety standards.With the support of this Q&A system,on-site engineers can make timely and informed decisions in complex blasting safety management scenarios.
