摘要
针对巷道围岩为复合岩层且其变形难以控制的情况,在分析巷道复合围岩变形特点的基础上,提出了阶梯式立体支护技术。分析了阶梯式立体支护的原理和围岩控制机理,结合平煤公司现场实际进行了支护参数确定和现场实施。现场观测表明,复合岩层巷道阶梯式立体支护技术取得了良好的技术效果和经济效益。
In view of the conditions that it is difficult to control the deformation of composite rock roadway,roadway surrounding rock deformation characteristics was studied and stepped-dimensional support technology was proposed. Support parameters was determined through analyzing principles and surrounding rock control mechanism of this technology and combining with the actual site Pingdingshan company.Field observations indicate that stepped-dimensional support technology of composite rock roadway make a good technical results and economic benefits.
