Abstract

The embodiment of the invention provides a rock burst roadway bottom plate buffering and damping structure and an arrangement method thereof. The rock burst roadway bottom plate buffering and dampingstructure comprises an upper bearing layer, a middle filling layer and a lower flat layer which are sequentially stacked. The middle filling layer is formed by mixing high-rigidity convex smooth particles, low-friction sliding particles and deformable damage energy absorption particles. The structure is not prone to deformation and damage in a static load state, the middle filling layer can generate rapid sliding dislocation and compression deformation under the impact load effect of a bottom plate, part of energy is absorbed and consumed, the function of attenuating impact waves of a weak interlayer can be achieved, and therefore the impact speed and release of the impact energy on the surface of the bottom plate can be greatly reduced, and impact damage of a roadway to the bottom plate is avoided. Meanwhile, compared with an existing independent supporting and reinforcing measure, the structure has the advantages that process is simple, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a shock-absorbing structure and an arranging method for the floor of a rock burst roadway. Background technique [0002] Rockburst is a major dynamic disaster encountered in coal mining. It is a dynamic phenomenon characterized by sudden, sharp and violent damage caused by the release of deformation energy of coal and rock mass around mine shafts and stopes. Simply put, rock burst is the sudden failure of coal and rock mass. my country is rich in coal resources, but the superior coal resources in shallow geological deposits are increasingly depleted, and it is an inevitable trend for the development of the coal industry to gradually shift to deep mining. With the increase of mining depth, rock burst disasters occur frequently, which poses a serious threat to coal mine production safety. [0003] Rockburst disasters have caused great damage to the roadway, among which the impact ...
