Shafts have many advantages and are used in constructing tunnels. When the position and course of the tunnel are correctly aligned and accordingly set out on the surface, shafts are sunk at defined points on the tunnel line to aid tunneling […]

The amount of sodium in the soil is the key measure of sodicity and is referred to as the Exchangeable Sodium Percentage (ESP). Sodicity in soil degrades soil properties by weakening the bond between soil particles. An […]
