SYSTEM OF MINE VENTILATION.
Application filed January 29, 1909.
Specification of Letters Patent.
Patented June 15, 1909.
Serial No. 475,034..
To all whom it may concern:
Be it known that I, DOMENIOO BELLONI, a citizen of the United States, and aresident of Edri, in the county of Indiana and State of Pennsylvania, have made certain new and useful Improvements in Systems of Mine Ventilation, of which the following is aspecification.
My invention relates to improvements in means for ventilating mines. It is especially applicable to the ventilation of coal mines in which noxious gases are liable to accumulate, but it is also applicable to any mine in which the removal of foul air is de sirable.
The main object of my invention is to provide means by which fresh air may be continually supplied to the miners and the foul air, together with the dangerous gases, may be drawn off separately.
A further object of my invention is to provide means by which the ventilation of a mine may be accomplished effectively at all stages of the work, so that every part of the mine in which the work is being carried on is being ventilated, thereby rendering the mine safe for those who are working it.
A further object of my invention is to provide means whereby the fresh air may be directed to the parts which are being worked, the old workings being cut off, so to speak, from the path of the incoming stream of fresh air, thus effecting a great economy in the power required to operate the air driving means.
My invention is illustrated in the accompanying drawings, in which- Figure 1 is a vertical section through a mine provided with my system of ventilation. Fig. 2 is a horizontal section through the mine along one of the working tunnels. Fig. 3 is a vertical section through the working rooms at right angles to Fig. 2 an enlarged detail view in section showing the location of the exhaust pipe. Fig. 5 is a horizontal section along the exhaust tunnel and through the vertical shafts.
A common system of mine ventilation is to force air through one shaft down around through the various workings of a mine and out of another shaft. Thus all the gases which accumulate in various parts of the mine are driven around through the mine mingling with the fresh air and the foul gases have to be inhaled by the miners as well as the fresh air. Where there is a great volume the walls h as shown. Fig. 4 is of fresh air brought in by a fan or other air moving device, this plan of ventilation works all right but it necessitates the constant forcing of a tremendous quantity of fresh air into a mine to successfully accomplish the purpose, otherwise the foul gases which are l mixed with this incoming stream of fresh air are conveyed by it from one portion of the mine to another before finally being driven out. In the present system the foul gases are taken out by separate means from the point at which they accumulate and are thus not distributed bythe incoming fresh air to the various parts of the mine.
Referring now to Fig. 1 I have shown therein a vertical section of the mine equipped with my improved ventilating means. This means consists of a vertical shaft which I will denote in general by A,
extending from the surface B of the earth N downwardly. The shaft is divided into three sections, a, b and 0, respectively, by partitions c and At the top of the passage a is a fan C, which is arranged to force air down the passage, while at the top of the passage 1) is a suction fan D designed to draw the air out of the passage. The third passage c is left open as shown.
My system of ventilation involves the use of the triple entry tunnels extending laterally from the main shaft. These tunnels are seen at E, F and G. The upper and lower tunnels E and F, respectively, are the working tunnels, while the central tunnel G constitutes an exhaust air passage which communicates with the central vertical passage through the medium of the bypasses g as clearly shown in Fig. 5.
in Fig. 2 I have shown the rooms at either side of the tunnel (in this case the upper tunnel E) these rooms H beingseparated by It will be observed that the tunnels extend on both sides of the main shaft A, a description of the workings on one side being sufiicient for an understanding of the workings on the other.
The exhaust pipes J, see Figs. 2 and 3, are disposed in the working rooms H leadingoif from the tunnels E and F in the manner shown in Fig. 3. Fig. 4 shows a detail view in which the pipe J terminates near the ceiling of the room and is provided with a funnel into which the foul air is drawn.
Referring again to Fig. 1 it will be seen that the upper and lower tunnels E and F are connected by means of a vertical cut K.
Between the cut K and the passage (1 is shown a similar out which has been filled in to provide continuous passages E, F and G, as will be hereinafter explained.
From the foregoing description of the arrangement of the shafts, tunnels and pipes the operation of the ventilating system will be readily understood. Fresh air is drawn in by the fan C at the top of the shaft or passage a and is forced downwardly in the direction shown by the arrow. When it reaches the first tunnel E it is deflected into the tunnel by means of the brattice L. In case the shaft is to be used for hauling up the mined material, this brattiee should be pivoted so as to permit the passage of the cage. The air then passes into the rooms H which adjoin the tunnel E and in which the work is being carried on. The foul air and gases tend to accumulate in these rooms and they are drawn out of the rooms by means of the suction fan D at the top of the passage 5, entering the ends of the pipes J as illustrated in Fig. 4, pasisng thence to the central exhaust tunnel G, see Fig. 3, and thence to the passage 1) by means of the passages 9, see Fig. 5, and out through the fan D. The excess of fresh air which is forced in by the fan C passes along to the end of the tunnel, thence down the vertical cut K and back through the tunnel F to the shaft and down the shaft to the next tunnel M, continuing around in the direction indicated by the arrows and finally escaping through the passage c to the air. It will be noticed that the central exhaust tunnel G is closed by means of a brattice 70 so as to shut off communication of the tunnel G with the tunnels E and F and the down cut K. The pipes 19, p and p communicate with the exhaust tunnel G and are preferably made or" flexible tubing so that they may be taken to the ends of these tunnels where the workmen are engaged in extending them as shown at Q in Fig. 1. As the sections of the tunnels are extended the brattice 7c is removed from the central exhaust passage to the succeeding one. The down out K is then filled up as shown in Fig. 1 and this makes continuous passages of the tunnels E, F and G as heretofore explained. The fresh air coming down the passage A is then first forced to the next down out K and back along the lower tunnel F and thence down to the next level. As the mined material in the rooms H is removed the openings 7L2, see Fig. 2, may be walled up, thereby confining the incoming fresh air to the tunnel.
incoming air aids in driving out the foul air and therefore one fan works in conjunction with the other.
This system may be applied to any mine by merely running the three tunnels in the manner described. It may be as successfully applied to old mines as to new. It is obvious also that instead of a vertical shaft, such as that shown, the entrance to the mine might be made by means of a tunnel or inclined shaft without departing from the spirit of my invention.
