Information × Registration Number 0205U006461, 0104U005852 , R & D reports Title To create the equipment for secure formation of unloading grooves by a hydraulic way at realization of raise access roads on flat seams, prone to sudden outbursts of coal and gas. popup.stage_title Head Dudenco Ivan Ivanovich, Registration Date 11-11-2005 Organization The state open joint-stok company Reserch and design institut "Uglemechanizatsiya" popup.description2 Object of researches is the installation for formation of grooves for access roads УПН, which one is intended for remote hydraulic creation of unloading grooves, and also hydraulic destruction between is whole at realization of raise access roads on outburst-prone flat seams of Donbass. The installation is intended for hydraulic creation of unloading grooves and for destruction between is whole without constant presence of the people at working faces at realization of raise access roads on seams, predisposed to sudden outbursts of coal on gas by power of 0,75-1,25 meters, pitch angle from 5 grades up to 20 grades and power coefficient up to 1,5 till М.М. Протодьяконову. The installation УПН is designed on replacement of the mechanical installations for formation of grooves. A method of fulfilment of activity: the analysis of the operation conditions, technological and commercial information. Main specifications: pressure of head of water - 20-30 МПА; Submission(supply) of high head of water - 200 l/ hours; diameter of bore well, which one forms by a module for formation of grooves of 120 mms; width of a unloading groove -80мм; depth of a groove 3,0м; a generation rate of bore well and unloading groove - from 0,1 till 0,6 m / hours; diameter of bore wells chisel выемочного of a body(organ) - is no more 200 mms; depth of bore well and length of a coal massif for 1 cycle подвигання of working face 2м; spacing interval of distance control - from 100 up to 200м.
