新疆某铅锌矿地面塌陷特征及评价

Characteristics and evaluation of surface collapse in a lead zinc mine in Xinjiang

金属矿产开采是当今社会发展的一个重要推动力,以金属矿地下开采为例,随着矿井建设与矿产资源的开采,矿区及其周围的地质环境难以避免地遭受破坏,其中又以地面塌陷为主要破坏因素。在新疆地区,生态环境脆弱的前置条件下,如何对地下开采的金属矿区进行有效的地面塌陷范围预测及治理尤为关键。本文在收集矿区的地质资料和现场勘探、调查数据的基础上,对新疆阿克陶县某铅锌矿区的地面塌陷灾害进行了现状与预测评估,对矿山地面塌陷特征做出了总结,最后根据地面塌陷情况与影响程度提出了相应的矿山地质环境防治措施。

The mining of metal minerals is an important driving force for the development of today's society.Taking the underground mining of metal mines as an example,with the construction of mines and the exploitation of mineral resources,the mining area and its surrounding geological environment are inevitably damaged,among which the ground collapse disaster is the main one.In Xinjiang region,under the preconditions of fragile ecological environment,how to effectively predict and control the surface collapse range of underground metal mining areas is particularly critical.On the basis of collecting geological data and field exploration and investigation data of mining area,the present situation and prediction assessment of ground collapse disaster in a lead-zinc ore area in Aktao County,Xinjiang are carried out,the characteristics of mine ground collapse are summarized,and the corresponding prevention and control measures of mine geological environment are put forward according to the situation and impact degree of ground collapse.
