| titleOfInvention | Near-horizontal coal seam-overlying rock-surface mining-motion true three-dimensional similar material simulation three-dimensional data acquisition method |
| abstract | The invention discloses a method for acquiring simulated three-dimensional data of a near-horizontal coal seam, overburden rock, earth surface mining, deformation and movement true three-dimensional similar material, which specifically comprises the following steps: scanning the surface of the working surface once, three times and two times by using a mobile three-dimensional laser scanner before, during and after mining to obtain point cloud data for realizing three-dimensional visualization of the subsidence basin; respectively arranging a settlement observation line on a top plate layer, a overburden layer, a bending zone and a loose layer on the boundary section side (a) of an upper (lower) mountain working surface and the section side (b) of a stratum surrounding the lower (upper) mountain working surface, and carrying out digital photography on a and b in a specific period in coal seam tunneling by adopting six mobile digital cameras to obtain macroscopic information of overburden deformation and internal settlement of the rock stratum; 5 stress monitoring lines are uniformly distributed from a to b in the coal seam top plate layer, the overlying strata and the loose layer respectively, and are connected with a computer through a stress sensing converter to transmit stress data in real time. |
