The solid backfilling mining method is one of the methods used to solve problems arising from strata and ground subsidence in underground mines. Through 2D physical analog modeling, 3D numerical simulation, and field measurement, the effects of the s

Shallow-buried, hard, and extra-thick coal seams are very common in Xinjiang, China, but there are relatively few studies on the mine pressure law and the development characteristics of water-flowing fracture zones (WFFZs) during the mining of such c

Abstract Based on the mining, dressing, backfilling, and X technology framework, we proposed the key operation indexes by exploring the principle, system, and integrated process of “mining, dressing, backfilling, and controlling” technology. Afte

To solve the problems of surface deformation and destruction of buildings caused by urban mining and realise the coordinated development of mining cities, the solid backfilling method was used to extract coal resources beneath the buildings of Tangsh

The research aims to explore the influences of lithology on the compaction behaviours of broken waste rocks. For this purpose, a WAW-1000D servo test machine and a self-made bidirectional loading test system for granular materials were used to conduc

Deep coal mining is unavoidable, and the complex mining environments and the increasing dangers associated with ultrahigh energy accumulation and release from mining disturbances renders it extremely difficult to maintain a safe and stable stope. Sol

There is a huge amount of solid waste generated in coal resource exploitation and utilization, leading to effects on the environment and hindering sustainable development. Aiming at the difficulty of disposal of coal-based solid waste from high-yield

Coal mine waste rock can be filled into the gob to control strata movement and protect the mine environment. However, the compaction behaviour of the waste rock backfill materials (WRBM) must be considered when the they are filled into the coal mine

Backfilling mining is a green mining method. The rational design of the compressed ratio of the backfilling body can reduce backfilling mining costs while avoiding mining-induced environmental damage. At present, the enumeration method is a common de

To study the mechanical properties of backfill materials during compaction at high ground temperature in deep backfill mining, the WAW-1000D electro-hydraulic servo universal machine was used to conduct compaction testing of crushed sandstones heated
