It leads to an increase the productivity and also to flush out the harmful and noxious gases to their permissible levels. This study is carried out to know the static conditions of mine which relates to the ventilation (i.e., Air velocity at roadways in mine, the existence of humidity in particular areas of the mine, the efficiency of fans at a rate of ventilating air into the mine, equivalent orifice (or) resistance of a mine, method of ventilating the air into mine, the ventilation distribution in mine and some other conditions). For ventilating the working faces, the proper controlling devices are used for coursing of air and sufficient ventilation survey techniques are to be developed to maintain the quality and quantity of air. This present paper covers a detailed view of the underground mine ventilation system, ventilation survey and different parameters that contribute to provide ventilation effectively.

INTRODUCTION Generally, as we all know that mining operations usually create a negative environmental impact both mining activity and also after the mine has abandoned this is because of, we are going averse to the environment there will be a lot of problems (or) difficulties occurs during the Mining operation like, (producing contaminant gases &dust during drilling, blasting, transportation, etc.,) in which reduces the miner’s efficiency &production (or) productivity of Mine. So, to conquer these difficulties ample amount of “Ventilation (or)Ventilation System” should be provided to the miner’s, who works in mines, normally the term ‘Ventilation’ describes, “It means by which fresh air is introduced and circulated throughout the building, while contaminated (or) stale air is removed (or) diluted”. In the view of mine ventilation, it is an important aspect of underground mining in which it is required to clear all harmful gases, as in coal mines removes fumes from blasting and occasional exhaust from diesel equipment and also at the same time it provides fresh air to the miner’s which improves their efficiency. so, the careful study of mine ventilation is needed and it is vital to create a safe and healthy environment. 1.1. Objective Here there are some objectives that we are going to give a brief explanation regarding the underground mine ventilation in which we are taking ventilation as our main objective or motive and the following objectives that we are going to addresses are:  To study different ventilation systems used in mines.  To study about ventilation parameters.  Detailed view of the ventilation survey. 1.2. Project Background The background of this project has been carried out (or) analyzed from the underground mine i.e., Kakatiya Khani -8 or 8A incline, Bhupalpally. The proposed project of an underground mine with a method of mining/technology (i.e. Bord and Pillar mining method). In which we have analyzed from the below-mentioned seams in mine they are,  1 seam average thickness of 2.5 mts to 3.30 mts.  2 seam average thickness of 2.5 mts to 3.30 mts.  3 seam average thickness of 3 mts to 3.60mts. 2. DIFFERENT TYPES OF VENTILATION SYSTEMS Depending on the type of mine and disposition of local geology, the ventilation system is chosen, the basic ventilation systems are:  U-tube system.  Through-flow arrangement system. 2.1.1. U-tube system: In u-tube system air flows towards and through the working area then returns along the adjacent airways, often separated from intakes by long pillars of stoppings. The airflow between the intake and returns is facilitated by access doors fitted in the stoppings.
