A mine consists of two stoping sections located at a depth of 2200m accessed by a shaft. If 10 rock drills are in the stoping section that is located a total distance of 1500m from the shaft and 8 rock drills are located in the second stope which is a total distance from the shaft bottom determine the pressure and quantity requirements of these rock drills. Both stoping sections area accessed from the same main drive.
Both stopes are accessed from this main drive by access drives that are 150m in length.
The average atmospheric pressure at the surface is 100kPa and a steel pipe conveys the compressed air.
There is no receiver in the system, thus assume the drills are working continuously. Hint to answer this you will need to undertake a pipe system design.
At a depth of 2200m, the average air temperature is 26 degrees Celsius and atmospheric pressure is 105kPa.
Assume g=9.81 m/s2, Density of water = 1000 kg/m3

The paper is about determine the pressure and quality require for the rock drills in mines which consists two stooping section which is located at the certain level of depth, it would be operated with the help of shaft and as it may access through the drive. The design and analytical solution is according to given data and as per mine engineering design. There were some of the assumption and standards data given which is taken care during calculation. The paper has been written prepare in Microsoft office words.
Perfect, no need of any kind of alteration in the work. It is delivered correct in first time only. what i need more. thank you expertsmind.
