REVIEW OF "MINING MACHINES FOR EXTRACTING MINERALS FROM THEIR BEDS"
BY A. M. TERPIGOREV, P. N. DEMIDOV,
AND M. M. PROTOD'YAKONOV
Jhe bc.. "Gornyye Mashiny dlya Vyyemki Plastovykh Poleznykh Iskopayemykh,"
was authorized by the Ministry of Higher Education USSR as a textbook for higher
institutes of mining education. Eight thousand copies, at 23.40 rubles, were
published in 1949 by the Ugletekhizdat; 500 pp and 377 illustrations.
The following represents Yevnevich's comments end critical review of sub-
ject book./
A brief outline of the development of mining machines and scientific re-
search on them. Data on the mechanization of extraction in the various coal
fields of the USSR; the organization of work; and the Stakhanovite movement in
the coal mines. Finally, a general classification of the various typee of min-
ing machines.
Part I. LONG WALL CUTTING MACHINES
Chapter 1. Introductory. General information on designation of machines,, etc.
2. Cutting bits. Requirements and methods of production.

5. Mechanical dust removers.
6. Reduction gears for working parts of cutting machines.
7-10. Feeding mechanisms for cutting machines.
11. Automatic regulation of feeding speed.
12. The electrical system of cutting machines.
13.. Technical exploitation of cutting machines (instructions and test
data).
14-:15. Organization of work. Brief .?zrvey of innovations since introduc-
tion of the continuous method of operation in 1931,
15. Analysis of output: efficiency of feeding system and labor.
Chapters 16-1'1. Inadequate consideration given to this type of machine by the
authors and the mining industry.
Chapters 18-27, These machines perform complex operations. Hundreds are in
use in the Donbass, Kuzbass, and Karaganda areas. This sec-
tion is inadequate in its classification of machines.
25 Flow sheet and cornposition of mining combines.
26. Peculiarities of Soviet mining combines. The KM-4 combine,
well covered in periodical literature, is not mentioned in
this work.

Part IV. DESCRIPTION OF PNEUMATIC DRILLS
Chapters 28-32. Not covered in this section are the theory of impact machines
and results .:f recent Soviet, research on increasing the useful
activity and decreasing the recoil of pneumatic drills.
Part V. BORING MACHINES
Chapters 33-36. Systematic description of boring machines, Insufficient anal-
ysis of trends of development of these machines.
fYevnevich emphasizes the "priority" of Soviet mining machinery in the
world and the advanced status of Soviet scientists because they have formulated
the subject "Mining Machinery" into a separate scientific curricul,.m of technical
schools. He remarxs about the great progress made by Soviet mining since the pre-
ceding edition (1940) of this book. He is particularly concerned with the proper
classification of aachines, the theory of their operation, and an adequate his-
torical account of their development. These are the principle bases on which he
criticizes subject book. In spite of the book's deficiencies in these lines,
however, he considers it as a definite indicator of the advance of Soviet science.
