- the mining method is fully mechanized mining. Collect the borehole data in and near the working face, and use the empirical formula corresponding to the hard rock in the "Code for Hydrogeological Engineering Geological Exploration of Mining Areas" to calculate the height of the hydraulic fracture zone. Some calculation results are shown in Table 1.
- the specific formula is as follows:
- H f is the height of the water-conducting fracture zone, m; M is the cumulative thickness of the coal seam, m; n is the number of coal strata.
- the layer above the number 1 is judged for the location of the out-of-straight development, and the number 1 layer is used as the first layer of the composite beam.
