Research On Aquifer Water Abundance Evaluation By Borehole Transient Electromagnetic Method Based On Fcnn, Cheng Jiulong, Wang Huijie, Xu Zhongzhong, Huang Qisong, Jiang Guoqing
Coal Geology & Exploration
Predicting the location and water abundance of aquifers by drilling or geophysical methods before tunneling is very important to prevent water disasters in advance for the safety of coal mine production. The use of borehole transient electromagnetic method (BTEM) for advanced detection has obvious advantages. At present, the interpretation method is based on the calculated resistivity to qualitatively analyze rock water abundance, and it is impossible to predict the aquifer water abundance grade. So, the fully convolutional neural network (FCNN) method is proposed to predict the aquifer water abundance grade for BTEM. Firstly, according to the Archie formula, Kozeny-Carman formula, …

Challenges And Solutions To High-Resolution Data Processing For Seismic Exploration, Cao Siyuan, Sun Yaoguang, Chen Siyuan
Coal Geology & Exploration
The seismic resolution has long been limited to the quarter wavelength. To compress the seismic wavelet, the key problems are signal-to-noise ratio (SNR) and resolution in early stages, and high resolution and high fidelity in late stages. Meanwhile, by using well data, many inversion methods of spanning quarter wavelength have been developed. The success of these methods depends on the preservation of seismic wave amplitude, the accuracy of seismic interpretation, and the compatibility between well data and seismic data. Afterward, researchers achieved seismic inversion without well data constraint, and the corresponding resolution reached the level of reflectivity. Meanwhile, the key …

From 1d To 4d: Advances And Thoughts On Coal Seismic Technology, Cheng Jianyuan, Zhang Xianxu, Jiang Bici, Wang Pan, Shan Rui
Coal Geology & Exploration
As one of the key technologies for safe and efficient support of coalmine geology, the seismic technology, has gone through one-dimensional (1D), two-dimensional (2D), and three-dimensional (3D), and progressed from resource exploration to mining area exploration, and from structural exploration to lithological exploration. The latest 4D seismic will further leapfrog from static detection to dynamic detection. Based on the concepts of time-space dimensions and the four seismic development stages, we propose three transitional stages from 1.5D (e.g., non-zero offset VSP), 2.5D (e.g., wide line 2D seismic exploration) to 3.5D (e.g., 3D seismic dynamic interpretation), and also present the time-space characteristics …

The shallow coal resources in North China have been nearly depleted so far, whereas deep coal development is challenged by karst water inrush in floor limestone. The conventional underground vertical hole grouting methods are troubled with inappropriate site location, thin drilling-met aquifer, large grouting blind area, and inaccurate target location. For this reason, we propose an advance regional control technology: bedding directional drilling-based grouting. We systematically study the slurry flow from near-horizontal grouting holes, advance grouting modes, grouting parameter control, advance identification of potential water diversion channels, as well as validation and assessment of a grouting treatment. On this basis, …
