چکیده
The article analyzes the issue of reliable estimate unloading extent and variation order coal-rock massif geomechanical characteristics as a result hydraulic fracturing undertaken from mine workings. For this purpose it is proposed to use value studied rock mass. In case possibility comparison with geological actual data doesn’t exist, option using mass classification based on estimated geophysical index that specifies considered. To address issue, survey active roof at excavation site in operating coal was implemented method seismic radioscopy before after fracturing. According results exploration, degree an has been determined.

Gas Drainage Improvement in Underground Coal Mines
Effective gas management is vital to the success of the longwall mining in the Bulli seam, in the Southern Coalfield, Sydney Basin, NSW, Australia. The evolution of gas drainage methods and practices are discussed with respect to gas type, gas drainage lead time and prevailing geological conditions. Both underground to inseam drilling and surface to inseam drilling techniques are described at b...
متن کاملRock dusting considerations in underground coal mines
Rock dusting to prevent coal dust explosions has been in widespread use in U.S. underground coal mines since the early 1900s. Underground coal mining technology has changed significantly over this same time period, becoming highly mechanized and produces finer coal dust particles which are more explosive. Despite the advances in mining technology, mine-wide dust sampling practices have remained...

متن کاملEnergy Analysis of Hydraulic Fracturing
In this paper, numerical simulations of circular boreholes under internal hydraulic pressure are carried out to investigate the energy transferred to the surrounding rock and the breakdown pressure. The simulations are conducted by using a micromechanical continuum damage model proposed by Golshani et al. (2006). The simulation results suggest that the borehole breakdown pressure and the energy...
متن کاملNoise variability in underground room and pillar coal mines.
Noise in an underground coal mine has dominant components generated mainly from 3 sources: (a) continuous mining machines, (b) roof bolters, and (c) cars/vehicles used to transport personnel and/or coal. Each of these 3 noise sources also has a number of well-defined sub-sources with their own noise characteristics. Sound level meters were used to collect noise data in the form of instantaneous...
