Nonimpact rock pressure regulation with energy recovery into the hydraulic system of the longwall powered support
نویسندگان
چکیده
The paper considers the advisability of continuous nonimpact regulation powered support unit hydraulic props resistance to roof rock subsidence. It also examined increasing adaptability within advanced high-powered mechanized longwall face complexes mining-geological conditions that change as blocks are extracted. A four-level characteristic with is proposed instead a typical three-level operating prop impact its Such operation modes power fluid displacement into pressure pipe can be provided by control unit. presents structure, connection diagram, and embodiment production in-mine testing MKYU 2SH13/27 equipped prototype were carried out on OOO Zavod Krasny Oktyabr loading test bench in A. D. Ruban mine AO SUEK-Kuzbass. data presented paper. possibility energy recovery system has been proved.

Numerical Analysis of the Interaction between Hydraulic Powered Support and Surrounding Rock Strata at Indian Longwall Faces
Longwall mining is the only technically proven and established method worldwide for coal extraction at greater depth. In this paper, 2D plane strain finite element models of longwall panels are developed and analyzed to understand the interaction of hydraulic powered support with surrounding rock strata. Based on Indian geomining conditions, finite element models are developed including the str...

This paper presents the results of engineering geological studies of rock blocks along a road tunnel in NW Iran. The tunnel is to cross the Western Alborz Mountain Range through 530 m in length with 11.2 m span and 8 m height. Eocene tuffs and andesites crop out in whole of the tunnel route. Numerical analyses are done using, a 3D stability analysis and visualization program, called Unwedge tha...

abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
