矿山地质灾害危险性评估中几个问题的商榷

笔者认为,为了合理、有效地开发利用矿产资源,在进行矿山地质灾害危险性评估过程中不要采用“禁采区”,建议采用围护带;在现行“规范”规定的基础上应根据各个矿山的具体情况可适当扩大围护带宽度,但不宜超过30m;在计算煤(矿)层顶板安全厚度的系数取值时,应考虑煤(矿)层倾角和围护等级;只有考虑了这些因素获得的地质灾害危险性评估结论,才具有适用性,才能真正为矿山设计和进行地质灾害防治工作提供科学依据。

Deliberation on the Several Matters in the Course of Evaluating the Risk of the Geo -hazards on Mines

For reasonable and effective development and exploitation of minerals resource,in author's opinion,the forbidden areas may not be adopted in the course of evaluating the risks of the geo-hazards on mines instead of safety berm in suggestion;the width of safety berm ought to be expanded basing on current standards and special conditions on each mine,but not suitably more than 30m;when calculating the coefficient values of safe thickness for the roof of the coal beds,the dip of coal beds and the grades of safety berm need to be considered;appraisal conclusion on the risks of the geo-hazards obtained in consideration of these factors just can provide scientific foundation for mine design and the works in performance against geo-hazards.
