On February 4, 1970, in the Fouquières-lès-Lens coal mine northern France, sixteen miners were killed a gas explosion (“firedamp,” grisou French). This was an accident like many others before it, yet with relatively high number of fatalities. The public prosecutor concluded, as usual, that there no case against publicly owned mine. No investigation to be carried out. had been work fate, bad luck.

The instrumental processing of the seismic event on January 6, 2022 t0 = 10:02:08.9 (UTC), ML 2.6, which occurred territory Komi Republic, is presented. application criteria for identifying earthquakes and explosions showed that was an induced earthquake. epicenter located in close proximity to Middle-Timan bauxite mine. Ore mining quarries carried out open way, where, among other things, blast...

Abstract– A mine ventilation system is an important component of an underground mining system. It provides a sufficient quantity of air to maintain a suitable working environment. Therefore, the mine ventilation system should be kept at a highly reliable level and also be maintained at a very reliable level during the whole service time of the coal mine. However, in reality, failures of a mine ...

Ensuring dust and explosion safety during underground coal mining is one of the most important tasks industrial labor protection departments. The main method preventing explosions settled in mine workings to process them with stone (rock dusting). traditional methods quality control rock dusting include radioisotope, optical chemical methods. To implement them, devices are equipped environmenta...

Today there is not enough scientific data on the energy level and velocity of an explosion in actual mine workings, which have a cross-sectional area larger than experimental workings. The objective paper to justify parameters workings based disclosure fire front development mechanism when coal dust explodes working with limited area. These studies can be basis for choosing speed action strengt...

With the continuous improvement of level intelligence in coal mines, construction sites have put forward new requirements for performance and compatibility mining computers. Aiming at field conditions intelligent underground drilling this paper designs a mine-used encapsulated intrinsically safe computer as data processing terminal, with characteristics large display screen, moderate overall we...
