  fracturing
Hydraulic fracturing in an inhomogeneous reservoir
      
A method of estimating the change in well productivity resulting from the hydraulic fracturing of a finite reservoir, piecewise-homogeneous in the horizontal and vertical directions, with an arbitrary number of cracks is proposed.
      
A correction coefficient that enables these estimates to take into account the effect of capillary trapping of mud and fracturing fluid filtrate is derived [1, 2].
      
The electric signals produced by fracturing rods made of different metals immersed in a high-temperature jet of combustion products are measured.

The experimental work on explosive fracturing in some rock formation with the liquid explosives has been summarized in this paper, in which the selection of the liquid explosive and technology of explosive fracturing is described in detail. The good result is thus achieved for the increase of permeability of the rock formation with the help of the blasting experiments using the selected liquid explosive.

In order to understand the abrasiveness of coal to mining machinery and its mechanism, abrasive wear tests have been made in a modified M-200 tester with steel of different carbon contents, using mining run coal, float coal and coal with different quartz contents as abrasives. The results show that when hardness ratio of coal to material, H_a/H_m, is greater than 0.64, the material experiences hard abrasive wear. However, the abrasive mechanism of coal is different from that of other abrasives, in that elasto-plastic...

In order to understand the abrasiveness of coal to mining machinery and its mechanism, abrasive wear tests have been made in a modified M-200 tester with steel of different carbon contents, using mining run coal, float coal and coal with different quartz contents as abrasives. The results show that when hardness ratio of coal to material, H_a/H_m, is greater than 0.64, the material experiences hard abrasive wear. However, the abrasive mechanism of coal is different from that of other abrasives, in that elasto-plastic deformation of coal grains takes place and causes the removal of material in the way of plowing-plastic squashing and flatteningcracking, which is similar to fracturing mechanism of plastic metals, little direct micro-cutting phenomenon occurs. The wear rate of materials is linearly proportional to quartz content in coal.

为了搞清煤对矿山机器的磨损作用及磨损机制,用不同碳含量的钢在改装的M-200磨损试验机上进行了原煤、浮选煤和煤中加不同石英砂含量的三体磨料磨损试验。结果表明:当煤和材料的硬度比H_a/H_m大于0.64时,造成材料的硬磨料磨损,但煤的磨料磨损机制同其他磨料不同。煤粒的磨料磨损特性是在其磨损过程中发生某些弹塑性变形,使材料以犁沟—塑变—最终造成材料的断裂而磨失。其过程类似于塑性金属的一般断裂机理,而直接的显微切削现象甚少。煤中的石英含量增加使材料的磨损率增大,磨损率和煤中的自由石英含量呈线性比例关系。

The mining procedures which have an influence on the stress field in the strata and the fracturing of the roof are the rate of daily face advance, the mining rhythm, and the nature of working. This paper deals with the mechanism of influence of these mining procedures and principle of adjustment in prediction.
