Feasibility Analysis of Drainage Equipment Design Scheme in Coal Mining Area
In order to ensure the reasonable selection of mine main drainage equipment,according to the relevant provisions of"Coal mine Safety Regulations",combined with mine development layout,report of predicted water inflow and total drainage vertical,four equipment selection schemes are proposed for the drainage system of 12 mining area.After comprehensive comparison,scheme 1 is selected as the drainage scheme of 12 mining area in the north of the mine.According to the drainage check calculation,the operation time of the selected drainage equipment is within 20 h during the normal water gushing period and the maximum water gushing period of the mine,the maximum shaft power of the equipment is 1212 kW,the motor power is 1400 kW,leaving 1.16 times enrichment factor,which meets the requirements of the mine.
