Research On Green Coal Mining Strategy In Hedong Coalfield Based On Resource And Geological Environment Characteristic, Liu Hanbin, Cheng Fangqin
Coal Geology & Exploration
Hedong Coalfield is located in the Loess Plateau of western Shanxi province at the western foot of the Lvliang Mountains in the middle reaches of the Yellow River. It is an important coking coal producing area, with severe soil erosion, fragile ecological environment, frequent occurrence of geological disasters and karst spring distribution in China. Through the analysis of resource and geological environment characteristics of Hedong Coalfield, it is found that the scarce coking coal reserves in Liliu mining area in the middle of the coalfield account for 70.8% of the total reserves. But its development intensity is higher than the …

Organic Geochemistry Of The Jurassic Tar-Rich Coal In Northern Shaanxi Province, Zhang Ning, Xu Yun, Qiao Junwei, Ning Shuzheng
Coal Geology & Exploration
The organic geochemical characteristics of tar-rich coal are of great significance to study the paleosedimentary environment and evolution of coal seams. Taking coal samples from 6 main coal seams of Yan’an Formation in Northern Shaanxi Province as the research object, this paper analyses the organic geochemical characteristics of coal seams by coal quality analysis and gas chromatography-mass spectrometry. The results showed that coal samples had a high abundance of chloroform asphalt "A" and a low saturated hydrocarbon/aromatic hydrocarbon ratios, characterized by the unimodal pattern of n-alkanes and dominated by medium chainsaturated hydrocarbons. The ratios of Pr/C17, Ph/C18 …

The rational development of tar-rich coal is of great significance to promote clean and efficient utilization of coal, improve the independent guarantee ability of oil and gas, and achieve carbon emission peak and carbon neutrality. In order to find out the occurrence characteristics of tar-rich coal in the typical mining areas of Carboniferous-Permian coalfield in Northern Shaanxi, based on coal exploration data and sample test results, this paper compares the tar yield of mineable coal seams, summarizes the spatial-temporal distribution rules of tar-rich coal, and discusses the occurrence influential factors. The results show that the average tar yield of mineable …

Gas Drainage Borehole Completion Technology Of Directional Long Hole Drilling With Negative Angle, Ma Zan, Chen Dongdong, Xie Hengxing, Chen Tianzhu, Wang Bin, Jia Bingyi
Coal Geology & Exploration
Pre-drainage of coal seam gas with directional long boreholes is an effective technical means to achieve advanced control of coal mine gas area. Affected by mining deployment, negative-angle boreholes(downward holes) are widely used in production. Medium-hard coal seams have good porosity and usually do not require hole protection. However, the existing conventional methods can not effectively solve the problem of water accumulation in negative angle long boreholes. This paper takes the downward long boreholes in the No. 9 medium-hard coal seam of Longfeng Coal Mine in Guizhou as the research object. Two sets of directional long boreholes are constructed in …

The Concealed Small Faults Detection Based On Gas Drainage Boreholes Along And Cross The Coal Seam, Xue Honglai, Wen Zhe
Coal Geology & Exploration
The faults have great influence on coal and gas outburst disasters, and accurate detection of faults location is very important to prevent such disasters. At present, large number of gas drainage boreholes were drilled in coal mines, but the geological information contained in these boreholes is not fully paid attention to, thus the method to detect concealed faults by gas-drainage boreholes was proposed. In this paper, by establishing a mathematical model for fault detection based on gas drainage drilling, a three-dimensional coordinate of fault planes and coal seam floors is calculated, and basic parameters such as fault location, drop, attitude …

Quantitative Study Of 3d Numerical Simulation On Optimizing Borehole Layout Spacing Of Gas Drainage, Chen Yuexia, Chu Tingxiang, Chen Peng, Tang Yang
Coal Geology & Exploration
In order to optimize the spacing of boreholes and realize efficient drainage, based on the fluid solid coupling model, a three-dimensional geometric model was established to make it closer to the field reality, the gas drainage processes of a coal mine with different borehole spacing were simulated using COMSOL software. The results show that: the effective drainage area was visualized by the three-dimensional diagram of the isobaric surface with gas pressure of 0.74 MPa, and the influence of borehole spacing on the extraction efficiency was discussed. The results show that: the effective extraction radius is about 1.5 m during gas …
