Journey Deep into the Earth #003
Even if these methods had completely eliminated the danger of hostile forces hidden in coal, geophysicists would not have been left without work in the mine: constant seismic and acoustic monitoring is now considered as natural as ventilation of underground workings. However, none of these techniques provides an absolute guarantee of protection against emissions. In some countries, even bacteria have been forced to protect mines. It's not as fantastic as it seems at first glance. Certain types of microorganisms have a great appetite for methane gas that accumulates in underground workings. If they are placed in an environment consisting of 99% of this gas, the bacteria will reduce this amount by 15% in a week. This is how scientists forced bacteria to perform one of the most dangerous professions in mining — gas burning. There was such a job once. Dressed in wet sheepskins, with his head tied up, a man entered the face when there was no work going on, and burned methane with a torch. Now it is possible to put gas-eaters in special containers and fill dangerous mines with them. However, this protection is also questionable, since gases located deep in the massif are involved in the release. Can bacteria get there, how soon will they overcome this difficult path, will they be as voracious in depth as on the surface? This is where even the "chosen ones" do not know what is being done in chemistry and biology of this so far only hypothetical method. All that was clear was that the pockets of explosive force accumulation, invisible to man, were located almost next to the face. But to say that it's somewhere close, or that an outlier is coming soon, is like saying nothing. It is necessary to accurately calculate the dangerous place or time when the underground forces will set the rocks in motion.
After all, the weather forecast service, for example, does not report a cooling or warming, but gives specific temperature and pressure figures: minus ten degrees Celsius, 750 millimeters of mercury. After geochemists, mechanics and other specialists came to the aid of geophysicists, something became clear. It turned out that the place in the coal seam, which accounts for the peak of rock pressure, is really located nearby, which is no closer than 3-5 m from the bottom of the face (this is what miners call the open surface of coal). It is in this place that convenient conditions are created for a sudden release. How many such dangerous places are there, say, per 100 m of face movement? To answer this question, it was necessary to find out the exact location of the origin of the impulses. After all, the accumulation of many small gaps in the coal in one place defines the danger zone. To do this, several geophones were installed in different places of the coal face (just as the sappers did with their wooden eavesdropping devices during the First World War).
