UNIVERSAL DRILLING MACHINE IN UNDERGROUND MINES

Universal Drilling Machine In Underground Mines (UDM)

It is a crawler mounted electro-hydraulic machine which can drill blast-holes in the face and also Drill holes for roof/side/floor bolting at various angle. hence it I known as Universal Drilling Machine (UDM).

 Universal Drilling Machine
The machine can drill holes from 38 to 63mm diameter and 3 to 5 meter deep. By adding more drill rods, holes upto 20m long can be drilled. Hence it is found very useful in blasting gallery panels also.
The UDM can work in gradient upto 1 in 4 and in seam heights upto 3.5m.
The height of UDM is  1.6m, length is 4.6m and width of UDM is 1m .
The travelling speed of UDM is 3km/h.
The machine is provided with a 22kw flame proof motor.

Safety Device In UDM

Rear Brake                                   
Parking Brake
Audio Visual Alarm
Canopy
Hand lever
Light
Foot switch 

Advantages

Due to speedy drilling production and productivity of loading machines (SDL, LHD) also increase considerably.
Handheld drill can not drill long holes but, UDM permits drilling of longer holes easily.
The UDM is provided with flameproof motor.
It has a strong canopy which prevent any fall of roof or object on the UDM operator.
By adding more drill rods, it can drill holes upto 20m long.
lights are provided, which provide sufficient light to UDM operator to work in underground mines.
It can move in narrow galleries and can take sharp turns.

SIDE DISCHARGE LOADER MACHINE (SDL) IN UNDERGROUND MINES

SIDE DISCHARGE LOADER MACHINE It is a popular coal loading machine of u/g mines. Which is mounted on the crawler track and is designed for loading the broken rocks on to a conveyor, in tub or to unload coal to the right or left of the machine. Being crawler mounted the SDL can work in gradient up to 1 in 4. It is totally flameproof machine, which make them suitable for operation in gassy mines.  Side Discharge Loader Machine A SDL has a bucket at front, which load the coal /ore from the face and transport or dump onto the chain conveyor, belt conveyor  which is installed near the faces or in tub and mine cars. All the movements of bucket are done hydraulically for which hydraulic pack is mounted on machine itself. The bucket capacity of SDL is 1𝒎^𝟑. The Motor capacity is 65 HP/ 550 V. the motor shall be DGMS approved and ISI marked. The SDL can work in distance upto 10m. Due to its crawler mounted it is not use for long distances. The SDL is ...

DRUM WINDING IN MINES

DRUM WINDING There are four different shapes of Drum used in India these are A)Cylindrical Drum. B)Conical Drum. C)Cylindro-conical Drum. D)By-Cylindro-conical Drum. CYLINDRICAL DRUM A Cylindrical or parallel drum is a simple and robust in construction. The winding ropes are attached at the end of the drum barrel, and arrange to coil on the drum in the opposite direction, so that when the drum rotates one cage will be raised and other lowered. The rope coiling underneath the drum is called  under lap. The rope coiling over the top of the drum is the   overlap. It may be either grooved or plain. Its serious drawback is that,  it can be used for shallow shaft only. In winding from deep shaft, the weight of one winding  rope will exceed the weight of the coal raised per wind. Thus there will an excessive load on engine when starting and negative loads towards the end of the wind causing heavy brake wear. This unbalanci...

LOAD HAUL DUMP MACHINE (LHD) IN UNDERGROUND MINES

LOAD HAUL DUMP MACHINE (LHD) LOAD HAUL DUMP MACHINE L.H.D is used in underground mines for the loading, hauling and dumping of the material from the working face. L.H.D’S  are used in more than 75% of the u/g mines throughout the world.  L.H.D are available in both Diesel & Electric versions. Diesel version is easily transportable from one location to another and have diesel engines as power drive of 75 to 150 HP or more. Engines are either water or air cooled. L.H.D with Electric motors as drives have general capacity of 75 to 150 HP. These are operative at medium voltage of 380 to 550 volts. Flexible trailing cables are provided with reeling/unreeling facility to feed power. In L.H.D machine an axial piston type motor is used. The maximum speed of L.H.D is nearly, 8-10 km/hr. when the  machine is Empty.  But when the L.H.D machine is loaded the maximum speed is 3-5 km/hr. The standard bucket capacity of the L.H.D is  1.6...
