Surrounding Rock Control Technology for Gob-Side Entry Retaining Under Goaf in Deep and Close Distance Coal Seams
نویسندگان
چکیده
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. The engineering practice shows adopting control technology, surface displacement body amount separation are all controllable range, stability is good.

Floor Heave Mechanism of Gob-Side Entry Retaining with Fully-Mechanized Backfilling Mining
Serious floor heave in gob-side entry retaining (GER) with fully-mechanized gangue backfilling mining affects the transportation and ventilation safety of the mine. A theoretical mechanical model for the floor of gob-backfilled GER was established. The effects of the mechanical properties of floor strata, the granular compaction of backfilling area (BFA), the vertical support of roadside suppor...
متن کاملStability Control of Retained Goaf-Side Gateroad under Different Roof Conditions in Deep Underground Y Type Longwall Mining
Stability of the retained goaf-side gateroad (RGSG) is influenced mainly by the movements of the roof strata near coal seam after coalface passes by. To make effective controlling technology for the stability of the RGSG, we analyze the roof structure over the RGSG to illustrate the mechanism causing the RGSG instability under different roof conditions. We then examine the dynamic evolution of ...

متن کاملGeotechnical considerations for concurrent pillar recovery in close-distance multiple seams
Room-and-pillar mining with pillar recovery has historically been associated with more than 25% of all ground fall fatalities in underground coal mines in the United States. The risk of ground falls during pillar recovery increases in multiple-seam mining conditions. The hazards associated with pillar recovery in multiple-seam mining include roof cutters, roof falls, rib rolls, coal outbursts, ...
