shown by the arrows, and the air, fresh from the shaft :19, sweeps around theentireworkingface 2 until. the door 24 againis en.-

From the inlet 23, the air follows a spiral course, to the main shaft 6, the means I for causing the air to move as aforesaid beving the door 25, the opening 15, the curtain 14, the door 12, the opening 16, the opening 17, the door'll, the opening 18, the door 25 again, and the opening 9. The coal is mined out along a number of long'straight faces, as shown at 2, and the coal is not driven ahead of the air, exploclosely adjacent to the box. 1

sions and fires being kept down accordingly.

The coal cutting is not done in'advance of an adequate supply of air, and there will be no pocketing of gas. t The miners cut around the outer wall of the mine and there is no occasion for taking the mining machine out from under the coal,- save for repairs. j 1. The plan outlined may be used in slope mines, as well as in shaft mines.

I claim 1. i In a mine comprising a chamber bounded by a continuous working face and having a main shaft extending down to said chamber, oppositely disposed loop-shaped tracks the outer portions of which cooperate to form :1 transportation means extended entirely around the chamber in convenient relation to said working face, the loop-shaped tracks comprising inner portions leading to the shaft.

2. In a mine comprising a chamber boundedby a continuous working face, a Wall defining a compartment inthe central part of thechambe'r, a main shaftleading down to. thecompartment, an air shaft discharging into the chamber, between'the .wall and the T working face, the compartment having an air ed from the wall to said continuous working face whereby-the air may circulate entirely
