INTRODUCTION

   A modern mine is difficult network of the mountain making, for ventilation of which apply a few energy sources and whole complex of vent buildings of different kind. Providing of making the required expense of air it one of main tasks, decided ITR areas of VTB of coal mines and depressed services of mine-rescue detachments. At the same time complication of a vent network, its complication, non-linearity of equalizations, describing motion of air in the mountain making, do almost impossible the decision of this task without application of computers.

 

A urgency of a theme

  Now the majority of collieries is conducted with activities on depth from above 1500м and fall into prone sudden outbursts coal and gas. In this connection actual problems of airing of mining outputs become.

 

The purpose of activity    

   To conduct the analysis of airing, to develop and justify measures on perfecting airing.

   

 

The content of activity    

    In the given work the brief characteristic mine and prospect of development of works is described. The geological characteristic of a deposit, opening, preparation of a mine field, system of development, transport, airing and the planned schedules of end of stocks.  
   This mine belongs to I-y of category of mixtures which contain methane and dangerous on the explosion of braize therefore, measures are examined on the decline of dust-ladenness of mine air, on warning of explosions of braize and measure on localization of braize.
   Greater part of diploma work consists of calculation expense of air for ventilation of sheths, for ventilation of the paid off and supported making, chambers. Raschityvayutsya of loss of air through vent buildings which are located outside sheths. The amount of air, which needs a mine, difficulty of ventilation of mine, is then determined.

We count the quantity of air necessary for airing of mine, on example ОP«SY»TRUDOVSKY», it is defined under the formula:

Qsh=1.1(Qуch + Qp.v. + Qpod.+ Qpog. + Qк. + Qуt. ), m3/min,

where Qych –The total expense of air for airing sites, m3/мmin;

Qp.v.-The total expense of air for the isolated airing Preparatory developments, m3/min;

Qpod.- The total expense of air for the isolated airing supported developments, m3/min;

Qpog.- The total expense of air for the isolated airing of repayable developments, m3/ min;

Qк.- The total expense of air for the isolated airing of repayable developments, m3/ min;

Qуt.- Air leaks through the ventilating constructions located outside of the developed site , m3/s.    

the flank scheme of ventilation of mine (Quantity of shots - 6, volume - 163 KB)

The tail-piece of diploma consists of development of measures to on: to the removal of external losses of air in mine-mouth complexes and mountain making; to diminishing of length of the mountain making which get some fresh air on a mine; to strengthening of pressurizing of vent buildings and devices impermeability of which makes less than 60%; normalizations of the thermal mode.

 

 

Conclusion    

    Degree work on a theme: "Тhe Analysis of a condition of airing and working out of actions for reduction of leaks of air in the conditions of OP "Shahtoupravlenie "Trudovsky" " is carried out on real working conditions of mine.  
   In it the detailed analysis of the state of ventilation of mine is given on a current period – 2009 year, and also the calculation of expense of air is produced, concrete measures are developed on his improvement on a current period, which allow to provide all objects and making of air a necessary expense, rationally to use crisp air for the minimum expenses of electric power on ventilation.
   
   Now master's degree work is in the stage of razraboki, in January, 2010 detailer information can be got for the author of Volkovoy Julia Pavpovny or for the scientific leader of Niсkolaeva Eugeny Borisovich.
