跨采条件下软岩巷道高强稳定型支护技术方案研究

By dynamic pressure influence of roadway deformation strongly, often repeated often repair it is still difficult to meet on expanding roadway usage section requirements, particularly close across mining under the condition of the soft rock tunnel, this paper through the tunnel of the geological condition, the deformation condition and roadway mine pressure appeared regularity, and analyzed LuLing coal mine Ⅱ 82 transportation up original supporting instability and failure reasons and puts forward the coal roadway supporting technical scheme and successfully applied in engineering practice.
