Abstract
1. The quantitative characteristics of the block size, found by processing measurements of the network of surface cracks, must be converted to the actual parameters of the block size; as a rough approximation we can recommend a linear transformation of the dimensions of the form (1), (2). 2. Borehole measurements of jointing in fans of blastholes enables us to obtain detailed and very important information concerning the jointing of the ore body; there is promise in the possibilities of operational monitoring, and in the use of this information to correct the method of charging and the scheme of blastholes when necessary. 3. Gamma-gamma density logging is a very promising method (although insufficiently researched in this application) of investigating the block size of the ore body-zones of deconsolidation, as a rule, correspond to regions of marked damage. A further step is the development of a method of measurement and quantitative interpretation of the GGDL curves interms of the jointing structure of the rock. 4. The geometry of single blocks (dimensions, area, volume, density, and shape) and their statistical aggregates (packing configuration, structural levels of jointing, and distribution of block dimensions) are important characteristics of the rock, and largely govern the effectiveness of a technology in particular conditions.
