To solve the technical problems in controlling surrounding rock of gob-side entry retaining deep and close distance coal seams under goaf, deformation failure characteristics goaf were analyzed this paper. Basic support inside roadway high-strength prestressed wire meshes, beam cable anchor, reinforcement single hydraulic with hinged roof roadside high-water material filling structure proposed....
In this paper, taking a typical roadway in broken and soft rock strata No. 10 Mine of Pingdingshan coal field as an example, the deformation failure mechanism mass was deeply analyzed based on testing. Then technology high-strength prestressed bolt-grouting support, such new combined grouting bolt, hollow anchor cable, were developed. Based this, repair support scheme using designed for on-site...
In order to study the stability control mechanism of deep soft rock roadway and active support technology anchor-grouting flexible bolt, this paper takes west wing transportation Yuandian No. 2 Coal Mine Huaibei Mining Co., Ltd., Huaibei, China as research background. By analyzing occurrence conditions failure characteristics surrounding structural mechanical properties combined with elastic–pl...
Background:Career anchor identifies job-related values and capabilities. Eight career anchors are: Functional- Technical, General Managerial, Autonomy & Independence, Security & Stability, Creativity & innovation, Serve & Dedication, Pure Challenge, and Lifestyle anchor. Each person has a special career anchor. Knowing the career anchors of employees is important both for the individuals them...
In this study, in order to examine the joint of the cable and the collar in control of scour around the bridge piles, experiments were carried out in a rectangular plexiglass flume as a direct path. The experiments were carried out using three different cable diameters, three different thread angles and three rounds of the cable threaded at a steady current in clear water. The results of this s...
With the continuous development of urbanization and rapid science technology, requirements for foundation pit engineering are getting higher higher. Foundation is gradually developing in direction larger area deeper excavation. In examples, combined supporting structure a pile–brace pile–anchor pits widely used, while examples supported by pile–anchor–brace system less frequently used. Based on...
