Strata behavior at fully-mechanized coal mining and solid backfilling face
Taking Ping Dingshan Coal Mine Group 12 as an example, this paper explains the system layout, key equipment and backfilling technology in detail. It probes into the characteristic of rock strata movement behavior and surface deformation above the gob area through in-site measurement method. The results show that as the overburden strata are effectively supported by the backfill body in mined ou...
متن کاملCharacteristics of Strata Behavior during Thick Seam Mining by Fully-Mechanized Top Coal Caving in a Loess-Covered Gullied Region
This study systematically investigates the overburden movement and strata behavior at a fully-mechanized top coal caving (FMTCC) face in a thick coal seam in a loess-covered gullied region by field measurement and theoretical analysis. A comparative analysis was performed to examine how the attitude of surface gullies and the structure of overburden affect face support resistance. The character...
متن کاملHealth Effects of Coal Seam Gas - Tara
I visited Tara on 11 and 12 October as requested, to undertake a review of individuals who believe their health has been adversely affected as a result of coal seam gas exploration being undertaken in the region. Queensland Health provided the consultation room with the Tara health facility, and also advertised my attendance, and made appointments for those families and individuals who telephon...
متن کاملReduction of Stress Acting on a Thick, Deep Coal Seam by Protective-Seam Mining
Aiming to reduce the high mining stress observed in large-space roof structures during mechanized mining of thick coal seams, a control technique based on protective-seam mining is proposed. This technique was used to investigate the 8108 working face of the No. 3–5 thick coal seam of the Tashan mine located in the Datong area of Shanxi, China, by means of simulations and field measurements. Th...
متن کاملGreen and Sustainable Mining: Underground Coal Mine Fully Mechanized Solid Dense Stowing-Mining Method
China produces and consumes most of coal in the world. This situation is expected to continue within a certain period in the future. Currently, Chinese coal industry is confronted with several serious problems relating to land resource, water resource, environmental, and ecological sustainability. Coal resource exploitation causes the permanent fracture and movement of strata structure, which h...
