摘要

摘要: 针对煤矿井下钻探存在孔底工程参数测量困难、钻探数据准确性和完整性不足、钻探数据融合应用不够等问题，设计了一种煤矿井下钻探数字化监测系统。该系统由数据来源层、虚拟模型层、数据处理层和钻探服务层构成：数据来源层为虚拟模型层提供数据支撑，虚拟模型层通过仿真模拟分析生成新的数据并反馈至数据来源层；数据处理层接收到数据来源层和虚拟模型层提供的数据后，进行数据清洗、转换及合并等处理；钻探服务层通过后台数据管理端的权限设置，为不同层级用户提供数据显示、查询、分析、报警等服务。将钻探数据按时序特征分为事前数据（钻探施工之前根据钻孔设计资料和施工方案等获取的数据）、实时数据（包括钻探过程设备实时监测的参数和钻场视频等）和延时数据（孔底随钻测量装置采集的参数），针对这3类钻探数据设计了数据处理流程，并建立了由接入层、汇聚层和核心层组成的系统通信网络架构。工程实践结果表明：该系统实现了煤矿井下钻探施工数据的采集、传输、显示与动态管理，满足钻探施工过程监测和数据管理的需求，具有较好的实时性和准确性。该系统为煤矿井下钻探智能化施工和精细化管理提供了技术支撑。

Abstract: A digital monitoring system for underground drilling in coal mines has been designed to address issues such as difficulty in measuring borehole bottom engineering parameters, insufficient accuracy and completeness of drilling data, and inadequate application of drilling data fusion. The system consists of a data source layer, a virtual model layer, a data processing layer, and a drilling service layer. The data source layer provides data support for the virtual model layer, which generates new data through simulation analysis and feeds it back to the data source layer. After receiving the data provided by the data source layer and the virtual model layer, the data processing layer performs data cleaning, transformation, and merging processes. The drilling service layer provides data display, query, analysis, alarm and other services to users at different levels through permission settings on the backend data management end. Drilling data is divided into pre drilling data (data obtained based on drilling design information and construction plans before drilling construction), real-time data (including parameters monitored by drilling process equipment and drilling site videos), and delayed data (parameters collected by drilling measurement devices at the bottom of the hole) according to temporal features. A data processing flow is designed for these three types of drilling data, and a system communication network architecture consisting of an access layer, a convergence layer, and a core layer is established. The engineering practice results show that the system has achieved the collection, transmission, display, and dynamic management of underground drilling construction data in coal mines. It meets the needs of monitoring and data management during the drilling construction process, and has good real-time and accuracy. This system provides technical support for intelligent construction and refined management of underground drilling in coal mines.
