POP 2010 program launched at Lazy Works is full of promise
LAZY - Assembling the 105 sections of DBT 2800/6000 with an outreach of six meters has reached the finishing stages at Karviná Mine, Lazy Works. Launching this high complex will represent its first run under the POP 2010 program not just at this shaft but also for OKD Corporation's entire mining district. Extraction will start at no. 139704-1 working face early in September, led by the gang of chief foreman Lumír Mosler.
But there were numerous measures that had to be in place before the installation proper of the sections could proceed – starting with leveling the surface rail track towards the shaft, including the erection of a new loading facility at the mine and the replacement of the normally used ZD 24A with the type ZD 24C/100 having a higher carrying capacity, and ending with enlargements/stripping to expand the profile of the working at both the entry and exhaust roadways.
According to Ivan Šrámek, Technical Director of Karviná Mine, the specificity of the complex is also due to the sections module and the working face conveyor sized at 175 centimeters, instead of the usual 150. Another novelty is the reinforced gantry system „jumbotrack“ of the coal-getting machine. In addition to DBT 2800/6000 (Bucyrus) sections, the face will be worked using an Eickhoff SL 500 cutter-loader and a PF6/1042 conveyor or a sub-face conveyor PZF11-PF4/1132 with type DU 3P5 crusher.
„The works connected with the installations of technology at the working face have so far been progressing according to the pre-set time schedule, and no major obstacles were encountered,“ the Technical Director said. The first workplace at Lazy Works to feature POP 2010 technology will be the mine's largest working face. Extraction is expected to move forward at the rate of three to four thousand tons a day, and this pace is expected to be maintained for at least nine months. Men at the shaft believe that the complex will be able to cope with the challenging geological conditions of the site.
