ture traces. Technical note. IIR. TRANS. SOC .MIN.ENGR .AIME,B,V8~, N822, MAY, 1975, P56- 58. A relatively simple system based on standard industrial optical components is described, which can be used to generate diffraction patterns for routine analyses of fracture arrays. The diffraction patterns are large enough to allow mo~itorlng of ratios between densities of fracture sets as an array is scanned.

In French. INDUST .MIN~. SER .MIN, N3,1974, P133-140. Tests used in different countries for measuring the mechanical properties of rock and abrasiveness are briefly described. Cerchar tests and results obtained from them are explained in detail in an appendix.

S~l scale Joint roughness measurements resulting from a series of direct shear tests on different model materials reproducing the roughness of natural rock surfaces are described, and the influence of Joint wall strength and wall roughness characteristics on the shearing resistance of the rock planes is discussed. Methods used to measure the roughness angle on a large scale are also described. 103~ TIXIER,MP LOVELESs, GW ANDERSON, RA Estimation of formation strength from the mechanicalproperties log. 13F,2T,17R. J.pETROLEUM TECH.V27,MABCH 1975,P283-293. The mechanical-properties log provides a quantitative means for identifying sands that are strong enough to produce oil and gas without any form of sand ccmtrol. The method is based on a correlation of in-situ strength with the dynamic elastic moduli computed from sonic and density logs.

89. A photogr~etric method for the measurement of positions and movements of points on the surface of a planar model of the rock mass is described. The method is theoretically based on the determination of the momentary position of a certain "mobile" point within the deformation plane by means of the coS/near transformation of its image coordinates, scaled on the image of the deformation plane, exposed in the given moment. Practical applications of the method are based on the application of modern surveying and co~utin~ antomates# limiting the quantity of the human routine work to minimum. This results not only in economical but also methodical effects in the area of the low-dlstance photogra~etry. Auth. 1042 ANONYMOUS Recommendations concerning static load tests of settling ground.
