摘要
烧变岩是由煤层自燃烘烤围岩而导致其变质形成的一类特殊岩石。笔者从水文地质问题、工程地质问题、物理力学特性以及固体废物可持续利用等角度出发,基于烧变岩自身特性,回顾了生态脆弱矿区烧变岩面临的水文地质问题和工程地质问题,并结合“资源利用、变害为宝”的观点,总结了烧变岩作为改性建筑材料和矿区充填材料的新用途,最后提出了烧变岩作为地质旅游景观进一步开发的潜力。笔者结合不同烧变岩固体废物颗粒掺量改性粉土的剪切性能可以看出混合土试样的抗剪强度指标黏聚力c和内摩擦角ψ均随烧变岩固体废物颗粒掺量增加总体表现出增大的趋势,由此说明烧变岩固体废物颗粒能够明显提高粉土的抗剪强度。通过对生态脆弱矿区烧变岩研究现状的分析及展望,可以进一步增进对烧变岩工程效应的认识,并实现烧变岩资源的可持续利用。
The burnt rock is a special kind of rock formed from surrounding rock baked by coal seam spontaneous combustion.Based on the characteristics of the burnt rock,the author reviews the hydrogeological and engineering geological problems of burnt rocks in ecologically fragile mining areas,from the aspect of hydrogeological problems,engineering geological problems,physical and mechanical properties and the sustainable utilization of solid waste,and summarizes the new behoof of burnt rock as modified building material and mine filling material combined the concept of“Resource utilization,Waste revaluation”,and ultimately,the author puts forward the potential possibility of burnt rock becoming a geological tourist landscape.Based on the laboratory experiments,the cohesive force and internal friction angle of the shear strength index increase with the increase of burnt rock solid waste particles content.According to the present situation and prospect of the study on burnt rock in ecologically fragile mining area,we can make further comprehension about the engineering effect of burnt rock and achieve the sustainable utilization of burnt rock.
