摘要
以近距离煤层回采巷道合理布置为对象开展研究,结合具体工程实际,在分析采空区底板下应力传播规律的基础上,运用数值模拟手段对极近距离采空区下巷道合理布置开展探究,希望能够为其他矿井相似工程的开展提供借鉴与参考。
Taking the reasonable layout of mining roadway in close coal seam as the research object, combined with the actual project, and based on the analysis of the stress propagation law under the floor of goaf, this paper used the numerical simulation method to explore the reasonable layout of the roadway under the extremely close goaf, hoping to provide reference for the similar projects in other mines.
