The paper analyzes the basal plane open volume of electric transmission line across mining influence areas,points out the semi-filling and semi-excavating slope protection method,narrow base tower,and concrete-filled composite big board foundation,and proves by the practice that the three ways can achieve the reduction of the basal plane open volume and environmental protection.%对输电线路经过煤矿采动影响区的基面开方量进行了分析,提出采用半填半挖的护坡方式、窄基铁塔以及中空混凝土复合大板基础三种减少基面开方量的措施,并作了详细研究,通过实践表明:采用上述三种方式达到了降低基面开方量,保护环境的效果。
