Ventilation Arrangement Grosvenor LW 104. Can Anyone Even Give It A Name? Who Dreamt This Up?

Ventilation Arrangement Grosvenor LW 104. Can anyone even give it a name? Who dreamt this up?

 

This plan was displayed during the Grosvenor Hearing today.

I paused the feed and took a photo with my mobile phone. which I have uploaded.

It shows how C Hdg runs parallel to B heading and bypasses the 400m sensor.

So are there 3 brattice stoppings on pogo sticks in the 3 cut-throughs behind the Tailgate of the Longwall?

Why are they not equipped with at least 20PSI (145 kPa seals if not 50PSI (345 kPa)because these would have been final seals if and when the panel was completed and sealed.

There should  be 50 PSI (345 kPa) Seals at least across the back of the goaf near where the vent shaft is located.

I have to ask again  who has dreamt this Ventilation Arrangement up.

Can anyone even give it a Name?
