Multifunctional mining surrounding rock impact shock shielding structure and method
The invention discloses a multifunctional mining surrounding rock impact shock shielding structure and method. The structure and the method solve the problems of surrounding rock water seepage, roadway damage caused by impact stress waves and the like in the mining excavation process, the shielding structure is a multifunctional layer and comprises an anti-seepage shielding layer and a wave-absorbing buffer layer, the multifunctional layer is located between exposed surrounding rock and a roadway, and the roadway is located on the inner side of the exposed surrounding rock. The anti-seepage shielding layer prepared in a spraying mode is tightly bonded with the surrounding rock, the surrounding rock is well solidified, meanwhile, the good anti-seepage effect is achieved, the wave absorbingbuffer layer prepared in a spraying mode is tightly bonded to the anti-seepage shielding layer, an integrated structure is formed, a good role is played in supporting and stabilizing, but also seismicwaves and stress shock waves are absorbed, and shock and noise generated in the roadway are absorbed, and the structure and the method are suitable for shielding and protecting roadway surrounding rock impact shock, and can effectively guarantee excavation, construction and use safety of underground engineering.
本发明公开了一种多功能用采动围岩冲击震动屏蔽结构和方法，解决的是采动开挖过程中围岩渗水及冲击应力波对巷道破坏等问题，该屏蔽结构为一种多功能层，包括防渗屏蔽层和吸波缓冲层，该多功能层位于裸露围岩和巷道之间，所述巷道位于裸露围岩内侧，通过喷涂方式制备的防渗屏蔽层与围岩紧密粘合在一起，不仅很好地固化了围岩，同时具有很好的防渗作用，同样通过喷涂方式制备的吸波缓冲层，紧密粘合在防渗屏蔽层上，形成一体化结构，不仅起到很好的支持和稳固作用，同时吸收地震波、应力冲击波，吸附巷道内产生震动、噪声，适用于巷道围岩冲击震动屏蔽防护，能有效保障地下工程开挖建造和使用安全。
