MK3E Middle Reamer Casing Drilling System DTH Drilling Bits ODEX146mm For Piling

Product name:MK3E ODEX146mm middle reamer casing drilling system for piling

Casing pipe OD: 146mm

Available for casing size from 89mm to 323mm.

Optimal drilling performance in unstable ground conditions. The eccentric bit can be easily and quickly removed for replacement or refurbishment.

Product components:

Pilot bit + middle reamer bit + casing shoe

Working principle:

1. When drilling starts , the reamer swings out and reams the pilot-hole wide enough for the casing tube to slide down behind the drill bit assembly
2. When the required depth is reached , rotation is reversed carefully, whereupon the reamer swings in , allowing the drill bit assembly to be pulled up through the casing.
3. Casing tubes that are to be left in the drill hole should be sealed at the bottom of the hole by means of cement grout or some other sealing agent.
4. Drilling continues to the desired depth in the bedrock using a conventional drilling.

FAQ:

1. Where does overburden go during a mining operation?
Overburden is used for reprocessing, contouring land, and as a construction aggregate for buildings and roads. Mine tailings are reused for producing clay, tiles, glass, and concrete. Mine water is treated and then used for dust and particulate suppression, agricultural/industrial use, and as a coolant.

2. What is groundwater drilling?

Basically, a well is a hole drilled into the ground to access water contained in an aquifer. A pipe and a pump are used to pull water out of the ground, and a screen filters out unwanted particles that could clog the pipe.

3.Why is overburden important?

In a petroleum system, the overburden rock overlies the source rock and contributes to its thermal maturation because of higher temperatures at greater depths. The age and thickness of the overburden rock determines the burial rate and thereby influences the heating rat.
