高应力软岩巷道支护压力及变形破坏机理的研究

随着矿山采深加大,深部高应力软岩巷道初期来压快,变形量大,软岩巷道自稳能力很差,如不加控制很快就会发生岩块冒落、巷道破坏.使用不适应软岩大变形特点的刚性架,也将很快被压坏,所以能否解决好软岩巷道的支护等问题,是煤炭开采向纵深发展和安全生产的关键问题之一.

Study on Supporting Pressure of High-Stress Soft Roadway and Deformational Destructive Mechanism

With the increasing of deep mining,the pressure and deformation quantity of deep high stress on soft rock roadway are large,due to the bad self-stability of soft rock roadway,rocks breakage and roadway destruction will occur if controlling methods are not properly performed.So the supporting problems of soft rock roadway is the key to deep mining and safety production.
