KQ90Y down hole drill with simple structure and lighter weight lower air pressure, could work easily at limited sites. Equipped hydraulic power will provide stronger power and less noise. The drilling sped is as 3-8timees as common low air pressure DTH drill.Drill the hole at the speed of 8-16m/h with the rock rigidity f=6-20. The drill is equipped with crawler unit,it is good for the small mining areas in the productivities of 200,000m3 annually, or serves as the auxiliary equipment of the large or medium mining to drill the side hole.
