The modern coal mines work at great depths, characterized by high natural gas content of the massif, which increases the intensity of gas release at high rates of movement of the working faces. A brief review of the experience of operating coal mines at great depths is given. The main directions of improvement of technological schemes of mine working areas are proposed.
Maintaining preparatory workings in good condition is one of the conditions determining the normal development of cleaning works. ...
Кафедра строительства горных пре д п рия т ий (СГП) в Ленинградском горном институте организована в 1947 г. Ее заведующим с момента организации до настоящего времени является профессор Б.В.Бокий. Первое время он был единственным преподавателем на кафедре и читал все специальные дисциплины горного профиля для специальности Строительство горных предприятий и курс “Проведение и крепление горных выработок” для специальности Разработка пластовых месторождений ...
Деятельность Петербургского горного института с первых лет существования отличала тесная связь с производством. Естественным следствием этого явилось участие его воспитанников и профессоров в создании угольной промышленности Донбасса, развивавшееся и углублявшееся по мере развития этой промышленности ...
November 13, 1965 marked 200 years since the organization of the oldest of the existing higher mining schools - Freiberg (GDR) Mining Academy. On this day in 1765 the project of the Academy foundation was approved, the educational work began in the spring of 1766.This anniversary attracts attention of figures of mining science all over the world, as Freiberg Mining Academy till the middle of XVIII century prepared personnel for the mining industry of 50 countries ...
Boris I. Bokii was born on July 23, 1873 in Tiflis, where his father was a teacher of a real school. Boris I. Bokii received his secondary education in Izium real school, which he graduated from in 1890. In the same year B. I. Bokii entered the St. Petersburg Mining Institute by competition and graduated in 1890. I. Bokiy entered the St. Petersburg Mining Institute by competition, which he graduated in 1895 in the first category, having received the qualification of mining engineer.
The first issue of the scientific printed organ of the Leningrad Mining Institute was published in St. Petersburg under the title “Notes of the Mining Institute of Empress Catherine II” on November 12, 1907, i.e. 134 years after the founding of the Institute. Until the beginning of the XX century its role was actually performed by the Mining Journal, founded in 1825 at the Mining Corps (as the Institute was then called) as an organ of the Mining Scientific Committee on Mining and Salt.
On January 4, 1954, Professor, Doctor of Technical Sciences V. D. Slesarev passed away. He devoted more than 35 years of his activity to the domestic mining industry and headed the Department of Development of Stratum Deposits at the Leningrad Mining Institute for 20 years. V. D. Slesarev was the first promoter of the introduction of longwall mining in the Moscow Basin. This method seemed impossible at that time, but is now considered the only appropriate one. V. D. Slesarev is the author of the first and original theoretically substantiated studies of the manifestation of rock pressure in the Moscow Basin. Based on his personal experience, V. D. Slesarev developed and scientifically substantiated such issues as the dependence of rock pressure on the shape of the cross-section of workings, the choice of their shape and methods of driving workings depending on specific conditions.
The terminology in the field of mining still contains many imprecise, polysemantic definitions and foreign words. This often complicates the correct understanding of the essence of the issue being presented and is the cause of mutual misunderstanding even between specialists in the same field. The struggle for the purity of the Russian language, the utmost precision and reflection of the technological meaning of special terms is extremely important. The work on the creation of a unified, correct terminology, which began several decades ago, is not finished and the terms developed by the Committee for Technical Terminology of the USSR Academy of Sciences are being adopted slowly. The establishment of uniformity of terminology in mining is a matter of extreme importance both in technical and legal terms. We will dwell only on some concepts related to opening and development systems, as well as the terminology of mine workings.
