When DTH drill bits for mining and dth button bits clean, the first thing to understand the cause of the sediment at the bottom of the bore.
1, digging DTH bit bucket tooth and residual between drill bucket bottom lid.
2, bottom cover closed is lax.
3, drilling mud, flow plastic formation, drilling dth drill bits in the drill pipe drilling slag erosion is serious in ascension, or sometimes even all loss within the hole.
4, digging DTH drill bucket outer edge cutting soil, due to the flat bottom of the hole could not enter the entry of the cylinder, and residue on the bottom of the hole's edge.
5, drill bucket bucket tooth is scanty, between tooth loss is inevitable.
6, drill footage back to the time is too large, loaded too full, waste residue from the roof drain out.
According to the characteristics of the mining DTH drilling method, we developed two methods of hole cleaning, achieved good effect.
At the same time, we can also by changing the proportion of sludge and mud soil and increase or decrease the viscosity of the slurry to control the speed of soil sludge settling velocity, for example, we try to reduce the soil sludge settling velocity, the preparation should be adapted to increase the density and viscosity mud, on the contrary, we can reduce the density and viscosity of DTH bit to speed up the mining slag soil sedimentation velocity.
Hole bottom sediment can't standard to do, so we must develop a hole cleaning, otherwise the large amount of settlement of pile top and bearing limit value is reduced, mining DTH drill hole cleaning settlement and displacement method, commonly used method is the so-called sedimentation method, after the end hole for soil slag precipitation to the bottom of the hole to hole cleaning, and replacement method is in the final hole on the bottom of the hole cleaning, immediately after the residue in soil has not been deposited from the mud before the hole with a new configuration of mud mud displacement in a way outside the hole.
And reverse circulation drilling, for use in pulp hole overburden drilling systems cleaning is appropriate, because it can take advantage of itself of digging in plasma of positive and negative circulation DTH drill, and spin dig with drill pipe does not transfer the function of the circulating fluid, want to use the method of black hole, also need to make DTH drill pipe and the corresponding mining equipment, this is obviously not feasible, and the settlement method is often used catheter suction pump, air lifting method, method of submersible slurry pump.
There are also some problems in using these methods, mainly the influence of slag suction mouth, when the aperture of one point five m, if can't move or hole bottom slag suction mouth position without tools churn, is away from the radius drill slag is more difficult to clear.
