A new solution

for an old problem…

slide2

Does your mine have

this problem? If it

does, you need to get

the Ker<><Thob

implemented into

your roof control

plan!

slide4

Ker<><Thob

Application

&

Installation Process

slide5

Any steel pipe, stronger than the roof bolt can be used with the Ker<><Thob, as long as it’s inside diameter is between (2.125 to 2.6 inches for our 2 1/8 inch unit) or (2.25 to 3 inches for our 2 1/4 inch unit).

slide6

One miner can carry a temporary roof jack, a shoulder bag containing a few Ker<><Thobs, two channel locks, and a selection of pipe cut to different lengths. This is all that is needed to allow one man to repair several loosened roof bolt plates.

slide7

Make the area

safe before

proceeding to

install the

Ker<><Thob.

slide9

Raise the loosened

roof plate up to

the roof and

measure the

distance from the

plate to the flange

of the bolt head.

slide10

Subtract two inches from the measurement to get the correct length of pipe needed to be used with the Ker<><Thob. (5”– 2” = 3”) pipe length needed

slide11

Select the

precut pipe

from the

shoulder bag.

slide12

Set the split halves of the

Ker<><Thob onto the flange of the bolt head.

slide13

Make sure that the notched ends of the split halves are resting on the flange of the bolt head!

slide14

Slide the spacer

pipe over the

bolt head and

the split halves.

slide18

Two Channellock Pliers (one 420 and one 460), and a tape measure are the only tools needed for the installation of a Ker<><Thob!

slide19

The Ker<><Thob was tested by MSHA on 10/3/96 and 9/3/97. Both times it was subjected up to 60,800 pounds of pressure with no failure.
