Abstract:

In order to solve the problem of controlling the roof of the stoping roadway in 1204 fully mechanized face under the influence of advanced support pressure, according to the characteristics of the stoping roadway section, the single hydraulic prop and π-shaped steel beam were selected to verify the shrinkage of the single hydraulic support and establish mechanics. The model calculates that at least 3 single hydraulic props and at least 2 material lanes are required for the transportation lane; through the numerical simulation method, a reasonable roof control plan for the stoping roadway in the advance support section is determined, that is, 0∼ in front of the material lane. The one-beam three-column method is adopted within 30 m, and the row spacing is 0.8 m; the one-beam four-pillar method is adopted within 0–20 m of the working front of the transportation lane; and the one-beam three-pillar method is adopted within 20–30 m, and the row spacing is 0.8 m. On-site industrial test practice proved that the proposed roof control scheme is reasonable, and the roadway section can meet the actual production requirements.
