Influence condition of ground on complexity in the process open pit Kuzbas`s coal deposits

Article preview

The complexity condition of ground in the process of open mining coal are determined inclination of seam, seam height, seam depth. It was confirmed by operations analysis recoverability benk. The dependence index of labour requirement and cost of mining operations on written factors was indentified. Magnitude of factors and gegree impact on technical and economic performance coal opencasts of  Kuzbass.

Connection content and properties of coal for quality control and quantity of coal-mining

Article preview

The correlation basic componentry of coal-mining as a natural result influence on ashcontent and internals coal of stratal assise, it predetermines physical and mechanical properties of them. Complex data about content and properties of coal is informative basis for engineering computation and mine technical action item for administration of quality and  quantity  coal-mining.

Perfection of the mine servey and geological maintenance of technology of open mountain works

Article preview

The factors influencing for open mountain works are established, bases of geologo-information model, typification of mountain-geological complexity of working out of coal deposits of advanced ways and means primary geologiche-skoj are offered the information. An effective method of a supply with information mine works is drawing up of the geologo-technological passport dredge-face. For mine works and their key process – drilling and explosive works the most significant geologists-cheskie the factors which are subject to studying and use for drawing up of passport drilling and explosive works are established. Skilled detonation confirms expediency of the offered improvements and use of laws of the geological factors, influencing crushing of breeds.

Forecasting by middle stratum ash content powerful compound structure deposits

Article preview

Forecasting of average ash content compound structure of coal deposits with split-hair accuracy is provided with use of the statistical information about ash content coal packs, differentiation on lithogenic. Use of average values ash content for coal as a whole without its division on structure leads to less exact look-ahead estimation middle stratum of ash content.

Consideration of the effect of humidity on the volumetric density of coal in the calculation of its reserves

Article preview

The evidence for the inverse relationship between volumetric density (apparent mass) and the natural moisture of coal in the massif is given. Natural moisture is proportional to porosity, which is inversely proportional to the bulk density. This pattern must be taken into account in the calculated method of determining the volumetric density of coal in the massif. When estimating humidity from samples, which is usually less than the humidity of the corresponding seam, the determined density of coal in the massif is higher than the density of coal in the sample. In this case, the correction for moisture has a "plus" sign, which is caused by another pattern associated with incomplete filling of the pore space with moisture in the sample, compared with the full water saturation of coal under natural conditions in the array.

Geological and mining and geometric preconditions for the forecast of fracturing of aged sedimentations of various ages in the Irkutsk Region

Article preview

Lithogenetic crackships is spread in all parts of Irkutsk Region. Its genesis is the result of influence of all complex crackform tense, that is made by endogenous litiphication process and tectonic movements. Distribution of lengthwise, trransversal and diagonal systems relatively syngenetic deformations and structures is the basis of prognosis of crack system direction, quantity and reciprocal relations.
