The two bulbs shown were used to extract methane air mixtures from the roof or roof cavities, and feed into a gas detector or specially adapted flame safety lamp. This would determine the percentage of methane present. The wooden baton would have been used to sounds the roof for cracks and also, used to ram 'stemming' into a shot-hole on top of the explosive.
