Adaptive intelligent cutting technology of the shearer based on the high-precision three-dimensional dynamic geological model

Publication Type: Academic Journal

Source(s): 矿业科学学报, Vol 8, Iss 1, Pp 26-38 (2023)

Abstract: If the shearer is cutting coal using the "memory cutting" technique, a manual demonstration is required.The memory cutting technology has higher requirements on the reserving conditions of coal seams.When the coal seam fluctuates greatly, frequent manu...

Publication Type: Academic Journal

Source(s): 矿业科学学报, Vol 7, Iss 6, Pp 752-762 (2022)

Abstract: In order to fully understand the current research situation in field of deep coal mining, took the relevant literature of web of science database from 2003 to 2021 as a sample, this paper made an in-depth analysis on the number of papers issued, resear...

The model of spatial analogous hyperboloid for three-dimensional rock strata movement in mining engineering

Publication Type: Academic Journal

Source(s): 矿业科学学报, Vol 8, Iss 1, Pp 1-14 (2023)

Abstract: Based on a large number of field investigations and the analysis of the "analogous hyperbolic" overall movement model proposed by the author, this paper further extends it to three-dimensional space, and proposes a full-space "analogous hyperboloid"thr...

Preparation of CaCl2-heat treated coal slime based composite catalytic material and its performance toward phenol degradation by activating peroxymonosulfate

Publication Type: Academic Journal

Source(s): 矿业科学学报, Vol 8, Iss 1, Pp 127-136 (2023)

Abstract: Based on the current situation of comprehensive utilization of coal slime in China and the urgent need for water pollution control in coal mining areas, this paper uses coal slime(CS)as raw material and CaCl2 as the activator, different proportions of ...

The drilling parameter acquisition system of hydraulic anchor drilling rig in coal mine roadways and its application

Publication Type: Academic Journal

Source(s): 矿业科学学报, Vol 8, Iss 1, Pp 66-73 (2023)

Abstract: The drilling identification technology of surrounding rock lithology can obtain the mechanical parameters of the surrounding rock of the roadway in real time, providing the basic guarantee for the surrounding rock support of the coal mine roadway. Base...

Research of high pre-stress NPR support technology in deep shaft roadway engineering

Publication Type: Academic Journal

Source(s): 矿业科学学报, Vol 8, Iss 1, Pp 50-65 (2023)

Abstract: Deep coal resources are the crucial backup for China's energy security in the future. However, large deformation and instability of rock mass in deep roadway engineering still poses serious problems in the deep "three high and one complex" geomechanica...

Application progress of molecular simulation in phosphate ore flotation

Publication Type: Academic Journal

Source(s): 矿业科学学报, Vol 8, Iss 1, Pp 102-114 (2023)

Abstract: Flotation is the main method to improve the quality and reduce the impurity of calcium magnesium phosphate ore. However, the similar surface physical and chemical properties of dolomite and fluorapatite make it difficult to separate efficiently. With t...

The key causes and characteristics of spontaneous combustion of coal seams affected by igneous intrusion

Publication Type: Academic Journal

Source(s): 矿业科学学报, Vol 8, Iss 1, Pp 15-25 (2023)

Abstract: In order to find out the key causes of changes in spontaneous combustion characteristics of igneous intrusive coal seams, this paper took the Daxing Coal Mine in Tiefa Coalfield as example for analysis, which was widely invaded by igneous and had serio...

Review of environmental impact of comprehensive utilization of phosphogypsum

Publication Type: Academic Journal

Source(s): 矿业科学学报, Vol 8, Iss 1, Pp 115-126 (2023)

Abstract: Phosphogypsum is a kind of industrial solid waste produced by wet phosphoric acid. Although there is an increase in the utilization rate of phosphogypsum, its consumption is limited. At present, it is still treated through accumulation, which will not ...

Research on the influence of blasting vibration on high-rise building near subway station

Publication Type: Academic Journal

Source(s): 矿业科学学报, Vol 8, Iss 1, Pp 83-92 (2023)

Abstract: Making clear the vibration response law of buildings(structures)due to blasting is of great significance both engineeringly and the economically. By conducting blasting experiment at subway station entrance A, the vibration signal of building NO.2 was ...
