基于一体化框架开发的新城金矿资源整合的探索

Exploration of Xincheng Gold Mine resources integration based on integrated framework development

矿产资源整合是解决矿山开发布局不合理等问题,实现规模化、集约化开发的重要手段,烟台市从政府层面推进矿产资源开发整合工作,实现了新城金矿一年内快速整合发证。尽管新城金矿是“焦家式”破碎带蚀变岩型金矿床的典型代表,具有矿体厚大的典型特征,具备机械化、一体化开发的潜质,但是新城金矿资源整合区涉及五个矿业权、130个矿体,整合区南北、东西的距离都超过4 km,面积达13.755 km^(2),矿体垂直埋深1 835 m,存在点多、线长、面广和超深井开采的突出技术问题。除此之外,国内采用多绳摩擦提升接近2 000 m井深的提升井尚无先例。如何将整合区内独立、松散的开发系统整合成一体化、安全高效的开发系统,仍是资源整合的核心和整合成败的关键。本文结合新城金矿整合实践经验,从一体化框架开发的视角,对整合区开拓系统、运输系统、通风系统、排水系统、尾矿利用及充填系统、地温地压防治系统一体化开发进行了探索,剖析了金矿超深井开采设计和金矿快速整合中的热点问题。本文梳理了复杂条件下金矿整合中一体化框架开发的思路及设计方法,增强了矿产资源整合工作的实效性,以期为其他金矿设计开发及资源整合工作提供指导和借鉴。

The integration of mineral resources is an important means to solve the unreasonable layout of mine development and realize large-scale and intensive development.Yantai City promotes the development and integration of mineral resources from the government level,and realizes the rapid integration and certification of Xincheng Gold Mine within one year.Xincheng Gold Mine is“Jiaojia Type”fracture zone altered rock type gold deposit of typical representative,has the characteristics of the large and thick ore bodies and have the potential to develop mechanization,integration.However,Xincheng Gold Mine resource integration area involves five mining rights,130 ore bodies,integrated area north-south,east-west distance is more than 4 km respectively,and it covers an area of 13.755 km^(2),1835 m ore body vertical depth.Between more points,long lines,wide surface and ultra deep well mining of outstanding technical problems,and domestic multi rope friction promote the ascension of nearly 2000 m depth of the well is without precedent.How to integrate the independent and loose development systems into an integrated,safe and efficient development system is still the core of resource integration and the key to the success of integration.This paper combines framework development,from the perspective of integration of framework development area of integration development system,transport system,ventilation system,drainage system,tailings utilization and filling system,explores the prevention and control of ground temperature pressure system integration development,analyzes the rapid integration of ultra deep well drilling design and gold mine in the hot issue.The purpose of this study is to sort out the ideas and design methods of integrated framework development in gold mine integration under complex conditions,and enhance the effectiveness of mineral resources integration work,in order to provide guidance and reference for the design,development and resource integration of other gold mines.
