Ground Response of Non-Coal Pillar Mining Panel
نویسندگان
چکیده
The mining-induced ground response (MIGR) has a critical impact on safety management, the mining plan, and entry support. A clear understanding of characteristics is foundation MIGRs scientific control. This study result development non-pillar panel with gob-side by roof cutting (GSERC). Comprehensive research in situ measurements, numerical simulation, theoretical analysis to determine characteristics, including GSERC, were implemented. results indicate that MIGR presents characteristic asymmetric near non-roof side more significant than side. stage convergence GESRC can be divided into seven stages; primary rapid should paid attention support process. rapidly increases 275 mm, 380 410 525 respectively, for rib virgin coal rib, side, middle section, hydraulic end cycle resistance at section value 30.8 MPa greater less 26 MPa, which feature. simulation regarding vertical stress development, displacement, horizontal displacement also division five divisions. Division II (the panel) IV range side) this provide technical guidance reference similar engineering practices.

متن کاملComparing the “Modified Split and Fender” and “Shortwall” Methods for the Pillar Recovery in Room and Pillar Coal Mining Using A 3D Finite Difference Modeling in Tabas Central Coal Mine, Iran
Selecting a suitable pillar recovery method is one of the most important issues in the room and pillar mining. The main purpose of this study is to compare two methods for pillar recovery in Tabas central coal mine (TCM). Among the existing methods, the two methods, “Modified split and fender” and “Shortwall” are chosen for the numerical modeling. The three dimensional finite difference method ...
متن کاملA Novel Longwall Mining Layout Approach for Extraction of Deep Coal Deposits
As more easily mined deposits are depleted, the reserves are becoming more limited and less favorable. Deposits of coal or trona that are being longwall mined are deep and are getting deeper. Coal bursts and bumps frequently occur within development entries in longwall mining of deep mines due to high stresses. This paper presents a novel patented longwall mining layout “Longwall Mining with Sp...
متن کاملAn Innovative Longwall Mining Technology in Tangshan Coal Mine, China
In mining of inclined coal seams in Tangshan coal mine of Kailuan group, gateways on either end of a panel were both typically located along the floor and a gateway pillar between adjoining panels was left unmined between adjacent panels to ensure stability, thus forming a planar mining system. According to the practice, however, it turned out that this conventional mining system has long-stand...
متن کاملStrength Reduction of Coal Pillar after CO2 Sequestration in Abandoned Coal Mines
CO2 geosequestration is currently considered to be the most effective and economical method to dispose of artificial greenhouse gases. There are a large number of coal mines that will be scrapped, and some of them are located in deep formations in China. CO2 storage in abandoned coal mines will be a potential option for greenhouse gas disposal. However, CO2 trapping in deep coal pillars would i...
