激光扫描测绘在地下矿井建模中的应用

Application of Laser Scanning Surveying and Mapping in Underground Mine Modeling

矿产资源是国民经济发展和人民群众生活保障的基础,而矿产资源开发利用危险因素多,很容易产生安全事故,直接威胁到开采人员的生命财产安全,最终影响到矿产资源有效利用。当前,浅层矿产资源开采殆尽,更多矿产资源都是集中在深部地质区域,只能使用井下开采方式,存在的安全隐患更多,增大安全事故出现概率,威胁到矿产资源的安全开采。基于这种情况下,矿产资源安全开采是非常重要性的,既会影响到矿产资源是否可以有效利用,也可以保障开采人员生命安全,还可以为矿企带来源源不断的经济收益。但是,以往采取的安全管理措施非常常规,更多依靠安全管理制度、安全检查等,无法对井下作业的具体情况进行实时监控,导致部分安全隐患无法避免。然而,在科学技术发展中,激光扫描测绘技术形成,为矿山建立信息化管理系统提供了技术支撑,有利于获取实时开采情况,从而提升矿产资源开采管理的安全性。本文通过对激光扫描测绘系统概述,阐述了激光扫描测绘在地下矿井建模中的数据采集流程和建模步骤,也对具体应用进行分析,为矿井建模工作提出了参考。

Mineral resources are the foundation of national economic development and people's livelihood security,and the development and utilization of mineral resources have many dangerous factors,which are prone to safety accidents,directly threatening the life and property safety of mining personnel,and ultimately affecting the effective utilization of mineral resources.Currently,shallow mineral resources have been exhausted,and more mineral resources are concentrated in deep geological areas.Only underground mining methods can be used,which poses more safety hazards and increases the probability of safety accidents,posing a threat to the safe mining of mineral resources.Based on this situation,safe mining of mineral resources is of great importance,as it not only affects the effective utilization of mineral resources,but also ensures the safety of mining personnel,and can bring continuous economic benefits to mining enterprises.However,the safety management measures taken in the past were very routine,relying more on safety management systems,safety inspections,etc.,and unable to monitor the specific situation of underground operations in real-time,resulting in some safety hazards that cannot be avoided.However,in the development of science and technology,the formation of laser scanning surveying and mapping technology provides technical support for the establishment of information management systems in mines,which is conducive to obtaining real-time mining information and improving the safety of mineral resource mining management.This article provides an overview of the laser scanning surveying and mapping system,elaborates on the data collection process and modeling steps of laser scanning surveying and mapping in underground mine modeling,and analyzes its specific applications,providing reference for mine modeling work.
