Full-text available
In China, as a major resource, coal has made great contributions to national energy security and social development. The mining of coal resources can cause surface subsidence damage, and , in particular, the mining of coal resources in thick loose layer mines is the most serious. How to accurately predict the surface subsidence caused by coal minin...

Coal mining in mountainous areas is general in China, especially in Shanxi Province. Under the influence of topography in mountainous areas, surface collapses and landslides caused by underground mining happen at a certain frequency and threaten human lives and assets. Accurate prediction of the movement and deformation of mining subsidence in moun...

High-strength mining has the characteristics of shallow buried depth, large mining height, and fast mining speed. Under the condition of high-strength mining, the overburden moves violently and the surface damage is serious. It has caused serious ecological security problems in the mining area. In order to solve this problem, it is necessary to ado...

Ground deformation measurements in mining areas play a key role in revealing the surface subsidence law, retrieving the subsidence parameters, warning of geological disasters and restoring the surface ecology. With the development of science and technology, there have emerged a great number of monitoring techniques and buildings of diverse protecti...
Article
Ultra-thick steep coal seam mining will inevitably lead to the increase of greater and violent ground subsidence and deformation. A subsidence control method by inversely-inclined slicing and upward mining is proposed in this paper. By this method, the sequence of collapse of overlying strata and the direction of propagation of strata movement are...

The mining of coal resources in eastern China has entered the stage of deep mining, and many mines have reached the depth of 1000 meters. Different from shallow and moderate depth mining, the temporal and spatial evolution regulation of surface movement and deformation under deep mining has its particularity. Combining with the geological and minin...

In modern life, metro and high-speed rails have become indispensable transportation and have been playing an important role in many areas, especially in cities. The metro and high-speed rails have varying degrees of impact on the surface and surrounding buildings, which must be carefully understood to minimize the risk of hazards. This work is aime...

Full-text available
Under the mining condition of extrathick coal seam, the overburden moves violently, the surface is destroyed seriously, and the discontinuous deformation such as cracks is fully developed. Taking Datong mining area as an example, this paper studies and analyzes the development characteristics and generation mechanism of surface cracks in loose laye...
Article
Full-text available
In mining engineering, after the extraction of underground resources, the maximum surface subsidence is usually less than the mining thickness of coal seam. However, under the condition of thick loose layer, some special phenomena appear in surface subsidence, for example, the maximum surface subsidence value is greater than the mining thickness of...
Article
High-intensity coal mining activities in China’s western mining area are damaging fragile ecological environments. The key to coordinating ecological protection and coal mining is to understand the law of overlying strata migration in high-intensity mining. However, it is difficult for conventional monitoring methods to efficiently monitor overburd...

The classification and segmentation of large-scale, sparse, LiDAR point cloud with deep learning are widely used in engineering survey and geoscience. The loose structure and the non-uniform point density are the two major constraints to utilize the sparse point cloud. This paper proposes a lightweight auxiliary network, called the rotated density-...

As an important power facility for transmission corridors, automatic three-dimensional (3D) reconstruction of the pylon plays an important role in the development of smart grid. In this study, a novel three-dimensional reconstruction method using airborne LiDAR (Light Detection And Ranging) point cloud is developed and tested. First, a principal co...
Article
Strip mining methodbackfill mining method and coordinated mining method are mainly used for strata movement control in China.But these methods with the disadvantage of low recovery ratio or high production.Soa new mining method was proposed that a small coal pillar is left and backfilling is performed on either one or both sides of the pillarfollow...

Differential interferometric synthetic aperture radar (DInSAR) technology is a new method to monitor the dynamic surface subsidence. It can monitor the large scope of dynamic deformation process of surface subsidence basin and better reflect the surface subsidence form in different stages. But under the influence of factors such as noise and other...
Article
The strata and surface movements have notable features of repeatedly mining subsidence cumulationwhen extra thick steeply inclined coal seam applied horizontal slice mining.And new prediction model was needed to establish for describing the shape of subsidence basin.Based on analysis of a large number of field observed data and similar model testac...
Article
A similar material simulation was conducted to study the special characteristics of the ground displacement and the surrounding rock deformation caused by mining activities of steep inclined multiple coal seams, based on the conditions at Muchengjian Datai Mine. The pattern of ground displacement and the collapse mechanism of surrounding rock were...
Article
The advanced working face model of DInSAR and GPS joint encryption observation was established based on the basic theory of mining subsidence. The two encryption times that are surge point and dramatic reduction point of surface subsidence velocity were obtained from this model. Therefore the effectiveness of surface dynamic deformation monitoring...

Using the advanced influence angles as examples, the calculation revision method is presented basing on the differential interference synthetic aperture radar (DInSAR) data obtained in West Cliff colliery mine in Australia. Through comparing the deviation between the actual advanced influence distance and the distance measured in DInSAR results, a...

The subsidence characteristics of horizontally-sliced mechanized top-caving mining are different from those of either flat seam mining or steep-inclined middle-thick seam mining. Similar material model test was used to simulate the rock mass movement of steep-inclined super-thick coal seam of a coal mine. The results revealed the law of strata move...
