Well-developed pores and cracks in coal reservoirs are the main venues for gas storage migration. To investigate multi-scale pore fractal characteristics, six samples of different rankings were studied using high-pressure mercury injection (HPMI), low-pressure nitrogen adsorption (LPGA-N2), scanning electron microscopy (SEM) test methods. Based on Frankel, Halsey Hill (FHH) theory, Menger sponge model, Pores Cracks Analysis System (PCAS), volume complexity (Dv), surface irregularity (Ds)...
Underground miners in Australia are facing continued threats from dust-related diseases. To address these issues, improved knowledge of airflow migration patterns and respirable dust dispersion characteristics within a continuous-miner-driven heading under an exhausting ventilation system is required. Based on site-specific conditions development New South Wales, three-dimensional computational fluid dynamics (CFD) model was constructed validated with onsite monitoring data, where good...
Abstract Moisture content of rock/coal can change its mechanical properties and absorption capacities, which directly affect gas diffusivity, the stress distribution hence cause significant impacts on overall or coal extraction process. Observation water penetration process in matrix will be beneficial for understanding fluid-solid coupling mechanism hydraulic fracturing, aquifer cracking seam infusion. However, observation determination mode were hard to non-destructively achieved as is a...
Abstract The traditional application of geocells is to place them in sandy or clay soils. However, considering the need for using coarse‐grained soils as embankment fill highways, this article proposes placing and conducting a series unconfined compressive strength tests study stress‐strain behavior. Specimens laboratory test were prepared cylinders with height 150mm diameter 1500mm, compacted 90%, 93%, 93% respectively. Three types planar geosynthetics commonly used reinforcement ‐ biaxial...
In solid backfilling coal mining (SBCM), the crushed gangue material (CGBM) is generally compacted circularly by a compaction machine in order to reduce its compressibility. this cyclic process, particles are crushed, which has significant effect on deformation resistance of CGBM. However, CGBM critical for controlling overburden strata movement and ground surface subsidence. This study implemented an experimental approach investigate particle-crushing characteristics acoustic-emission (AE)...
Abstract The gas content is crucial for evaluating coal and outburst potential in underground mining. This study focuses on investigating the in-situ seam sorption capacity a representative with multiple sections (A1, A2, A3) Sydney basin, where CO 2 composition exceeds 90%. fast direct desorption method associated devices were described detail employed to measure components ( Q 1 , 3 ) of seam. results show that total T ranges from 9.48 m /t A2 section 14.80 A3 section, surpassing Level...
In solid backfill coal mining (SBCM), loose gangue material (LGBM) is used to the goaf after resources are exploited from underground mines. Under certain geological conditions, LGBM with a height may be soaked in water, and then becomes saturated, significantly altering its mechanical properties. The confined compression experiments were this paper analyze deformation crushing characteristics of varying water heights results showed that large number small holes distributed blocks main...

The showed that inferior affected by behaved mode sliding...
Rock fragmentation is a common physical and mechanical phenomenon that exists in variety of ranges from the mining processing. Communication an important operation coal processing whereby block coming coalmines crushed into fragmentations with reduced size, which accounts for 80% electricity consumption mineral circuits. Fragmentation energy, related to particle size distribution, essential parameter improving efficiency shearer, road-header, crusher. Coal particles are generally simplified...
Spontaneous combustion of coal occurs in the longwall (LW) goaf during mining cycles due to oxidation at low temperatures and air ingress. Coal seam orientations, dictated by elevations maingate (MG) tailgate (TG) height working face starting-up line, significantly impact gas distribution goaf.
