The hanging of hard roof strata in the gob-side retaining entry in deep mines could lead to dynamic disasters. The pressure relief mechanism for the hard roof strata using shallow-hole blasting was investigated by a combined method of theoretical analysis, numerical simulation, and field test in the Sanhejian coal mine. The shallow-hole blasting model was established using LS-DYNA3D (Livemore. Highlights from the book include coal resources and distribution, mine design, advances in strata control and power systems, improvements in surface mining, ventilation to reduce fires and explosions, drilling and blasting, staffing requirement ratios, management and .   International Journal of Oil, Gas and Coal Technology; Vol No.1; Title: Surface subsidence control during bag filling mining of super high-water content material in the Handan mining area Authors: Xufeng Wang; Dongsheng Zhang; Chundong Sun; Yang Wang.

with respect to aspects of strata control, increases their exposure to such strata control risks. The primary objective of the Safety in Mines Research Advisory Committee (SIMRAC) project 02 02 07 was to develop tools for the transfer of strata control knowledge. Four such tools were developed, three of which focused on illiterate underground mine.

NSW code of practice: Strata control in underground coal mines Scope and application This code is a practical guide to assist the mine operator to identify and control strata failure hazards as part of developing and implementing a principal mining hazard management plan, as required under the WHS (Mines) Regulation.

This code applies to the. Strata control is the science (some would suggest art) of utilizing various techniques to prevent or control failure of the strata around mine openings at least for the period where access is required.

For different locations in the mine this period may be for the life of the mine (which can be considered as permanent), such as the main mine. Effects of environment (moisture, barometric pressure, and temperature) on strata control in coal mines have been studied in some depth in the past one decade.

Such effects become very important where shales, which are known to be sensitive to moisture, occur immediately above or below a coal seam being mined as in the Illinois coal basin. Measurement, Control, and Optimization in Mine () Edited by H.W.

Journal of the Institution of Civil Engineers. E-ISSN Volume 10 Issue 3, JANUARYpp. As the mining depth increases, under the influence of high ground stress, the surrounding rock of deep mine roadways shows soft rock characteristics.

Under the influence of mining disturbance at the working face, large deformation of the roadway has occurred.

To control the large deformation of the roadway, many mines have adopted the form of combined support, which has continuously increased Author: Chaowen Hu, Xiaojie Yang, Ruifeng Huang, Xingen Ma.

The stress distribution curves above key strata 1 and 2 with mining are respectively shown in Figs. 5 and 6. As can be seen from Figs. 4d, d′, 5 and 6, the cracks in the strata above key strata 2 are caused by the mining-induced stress concentration.

After the mining excavation, the redistribution of stress, characterizing with high stress. The text broadly covers recent developments in ground control techniques, and their at operating mines, worldwide. Specific topics include: design and analysis of support and re-inforcement in metalliferous mines, mesh, shotcrete and membrane support systems, and strata control in coal mines.

Coal strata are displaced by roof movement along planes of stratification and differential shearing of coal pillars, and floor strata mainly by heave deformations; within sub-level structures are stress-concentration zones, stress-relaxed zones with pushes of abutment stress of more than 50 m, and the influence of mining stresses for m.

There are two specialisations offered: Underground Ground Control and Coal Mine Strata Control. Students study fundamental principles of rock mechanics and geotechnical engineering, followed by a comprehensive coverage of practical strata control applications.

Deep mining in Northern and Eastern China is subjected to more threats from water disasters; and mining under pressure leads to frequent accidents caused by water disasters. It has been proved in corresponding literature that the depth of the floor failure is a key parameter for water disaster prevention and control of the floor of a working.

Aimed to control the stability of surrounding rock of gob‐side entry retaining in deep coal seams, in this paper, an innovative approach of BCR‐GER for deep coal mines is proposed, three key techniques of the approach are introduced, the mechanical model of “surrounding rock‐supporting body” is developed for key parameters.Strata Control may be defined as a risk management tool, which in part ensures the proper control of the mining environment to minimise the risk of local instability.

Effective strata control ensures that on a local scale, appropriate mining strategies and/or support actions are employed to overcome local & unforeseen or unpredictable changes.
