Abstract: Based on the measurement and analysis of the return air lane, this paper optimized the arrangement of transportation lane, which reduced the absolute number of hydraulic support need to be added or withdrew by 36 to 13; Put forward the bracket installation chamber achieved rapid adding hydraulic support, which reduced the operation time from 24 hours to 8-12 hours for adding one support; Put forward to using the rapid removing method with Pre-dug retreating channel withdraw the equipments, which reduced the influence of the production time by expected 10 days to 3-4 days, get the purpose of rapid adding or withdraw the hydraulic support in working face.
