| 摘 要： | 针对屯兰矿12206综采工作面瓦斯尾巷严重变形破坏的问题,通过现场实测和理论分析研究其破坏机理及控制对策,结果表明:富含黏土矿物的底板岩石在矿井水的楔劈作用下碎裂扩容产生膨胀应力；动压巷道在回采过程中产生高应力与剪切破坏；复杂动压及膨胀应力耦合作用导致巷道表现出强烈的流变特性；加强支护并阻止水对底板岩石的弱化是解决该尾巷大变形的必然选择；改性注浆加固技术,可成功解决软岩动压巷道的支护难题.

| Abstract: | For the severely deformation damage phenomenon of 12206 working face methane tailing gateway in Tunlan mine,failure mechanism and control technologies were researched according to field measurements and theoretical analysis.The results showed that floor rock rich in clay was disintegrating dilatancy and produced expansion stress under the wedging action of mine water.Dynamic gateway produced high stress and shear failure in the mining process.Roadway displayed a strong rheological characteristic,because of ... |
