The main objective of this study was to investigate the instant consistency cement-treated marine clay using fall cone test and Casagrande (percussion cup test) method. As a result, penetration depth cone, which determines liquid limit close value obtained by percussion cup, changed presence or absence cement. It shown that same sand content with much higher cement led smaller values. small amount highest; it then decreased increase in content. correlated additive ratio, is defined as ratio...
An analysis of the stiffness theory reveals that coal mass compression bumps occur only when both failure criterion and are simultaneously satisfied. Then a new structural factor called uneven seam structure (USCS) is proposed, which consists an along with continuous roof floor. The USCS serves dual functions pressure concentration reduction. former facilitates stress from low zone (LSZ) to high (HSZ), thus raising risk (rF) failure. latter reduces surrounding rock HSZ, allowing system meet...
The conventional fracture in shale hydraulic fracturing belongs to the type-I fracture, and size of process zone (FPZ) is an important index measure fracability rock mass. This also one feasible entry points study complexity network. In order visually observe FPZ at tip fractures, relationship between mechanical properties, shape FPZ, bedding structure, Notched Semi-Circular Bend (NSCB) tests were conducted with three typical direction-bedding orientations (splitter, arrester, divider)....
The development of stiffness theory is constrained by its contradiction with engineering experience. Several easily overlooked details were clarified, and a qualitative evaluation formula for the risk coal burst was provided. Then novel structure factor called uneven seam (USCS), which consists high zone (HSZ), low (LSZ), contiguous roof floor, proposed. Many areas prone to bursts, such as thinning zones, bifurcating areas, magmatic intrusion remnant pillar affected seam, are HSZs USCSs....
This paper investigates the preliminary stability of pillar linking adjacent caverns under effect water level differences. By choosing homologous rocks, permeability tests and Brazilian in laboratory are conducted. Then theoretical model solutions made. The results show that rock is extremely low. tensile strength tuff not very high, its will dramatically reduce due to long-term erosion. Under comprehensive joint fissure, prone slab typical lamellar structure. Especially, when span narrower...
