在分析煤矿高强度开采现状与定义的基础上,从地质采矿条件、工作面尺寸、技术装备、推进速度、产量效率高、深厚比、覆岩与地表破坏等方面系统研究了厚煤层高强度开采的主要技术特征。基于绿色开采理念,从地质采矿技术和采动影响破坏方面研究建立了高强度开采的主要技术指标和评价体系,并采用层次分析法对采动影响破坏指标进行了分析研究。研究表明,地质采矿技术因素和采动影响破坏因素均是描述厚煤层高强度开采的重要组成部分,采动影响破坏因素是厚煤层高强度开采不可忽略的特征。研究成果可为煤矿安全高效绿色生产、采动损害与保护等提供借鉴。

On the basis of analyzing the current situation and definition of high-intensity mining in coalmine,the main technical characteristics of high-intensity mining in thick coal seam were systematically studied from the aspects of ge- ological and mining condition,working face size,technical equipment,advance speed,high production and efficiency, ratio of depth to thickness,overburden strata and ground surface destruction. Based on the concept of green mining,the main technical indexes and evaluation system of high-intensity mining had been established from the aspects of geolog- ical and mining technology,and mining influence and failure. Meanwhile,the analytic hierarchy process ( AHP) was used to analyze the mining influence and failure index. The results demonstrate that geological and mining technical factor and mining influence and failure factor are important parts of high-intensity mining of thick coal seam. Moreo- ver,mining influence and failure factor is an important characteristic that cannot be ignored in high-intensity mining of thick coal seam. The research results provide a theoretical and technical basis for safe and efficient green production, mining damage and protection in coalmine.
