摘要

在迫切需要摆脱高等级公路下煤体压力的情况下，在调查高等级公路下煤体开采可行性的基础上，研究了高等级公路下煤体开采病害的机理，从结构(基础)组成和线性组成两方面，按秩序规范对高等级公路的安全抗力指标进行了分析;然后，结合前人的研究成果，结合国内外文献，提出了新的相应阻力指标，即水平变形 0≤2mm/ m;高等级公路及升级公路沉降w≤300mm;二级道路沉降w≤500mm。本文对高等级公路开展矿山开采具有一定的指导意义。

Research on disease mechanism and safe resistance index of high-grade highway in mining activities

In the urgent need for liberation from the pressure of the coal under high-grade highway, on the basis of having investigated the feasibility of mining under it, researched on the mechanism of its disease in the mining activities, security resistance index of high-grade highway is analyzed from the compositions of structure(Foundation) and linear, according to the norms of order; then, new corresponding resistance index is proposed, combining the results of former study with domestic and foreign literature, namely: horizontal deformation å0 ≤ 2mm/ m; high-grade highway and upgraded highway subsidence w ≤ 300mm; subsidence of secondary roads w ≤ 500mm. This essay is of certain significance for the high-grade highway to carry out mining.
