沿空留巷技术是煤矿开采及回采巷道支护技术的一项重大改革,现针对沿空留巷围岩变形大、力学特性存在较大变异的特点,采用理论研究、运用工程结构可靠性理论、岩石力学和弹塑性力学以及计算机技术等理论,围绕沿空留巷巷内锚杆支护、巷旁高水速凝材料充填支护方式的结构可靠性进行了比较系统的分析。
Gob-side entry retaining technology is a major reform of coal mining and mining roadway support technology. In view of the large deformation and mechanical characteristics of surrounding rock along gob-side entry retaining, using theory research and applying the theory of engineering structure reliability , Rock mechanics and elasto-plastic mechanics and computer technology and so on, the reliability of structures around bolt support in gob-side entry retaining lane and filling and supporting of high-velocity solidified roadside material are systematically analyzed.
