Underground microseismic monitoring of a hydraulic fracturing operation for CBM reservoirs in a coal mine

Autor: Zhizhong Jiang, Quangui Li, Qianting Hu, Jiufu Chen, Xuelong Li, Xiaoguang Wang, Yangcheng Xu

Publikováno v: Energy Science & Engineering, Vol 7, Iss 3, Pp 986-999 (2019)

Abstract Hydraulic fracturing can evidently improve the coalbed methane production in underground coal mines, but it is difficult to delimit the stimulated area accurately. In order to evaluate the stimulated area, microseismic (MS) monitoring techni

Analysis on the Initial Cracking Parameters of Cross-Measure Hydraulic Fracture in Underground Coal Mines

Autor: Yiyu Lu, Liang Cheng, Zhaolong Ge, Binwei Xia, Qian Li, Jiufu Chen

Publikováno v: Energies, Vol 8, Iss 7, Pp 6977-6994 (2015)

Initial cracking pressure and locations are important parameters in conducting cross-measure hydraulic fracturing to enhance coal seam permeability in underground coalmines, which are significantly influenced by in-situ stress and occurrence of coal

A Sequential Approach for Integrated Coal and Gas Mining of Closely-Spaced Outburst Coal Seams: Results from a Case Study Including Mine Safety Improvements and Greenhouse Gas Reductions

Autor: Liang Cheng, Zhaolong Ge, Jiufu Chen, Hao Ding, Lishuang Zou, Ke Li

Publikováno v: Energies, Vol 11, Iss 11, p 3023 (2018)

Closely-spaced outburst coal seams (COCS) is the main condition of coal seams in southwest China, and gas disasters are one of the major problems affecting coal mine safety. Mining a protective seam and pre gas extraction are the most safety way to i

Bridging role of Ag0 particles formed in-situ on Ag3PO4/BiPO4 composites for enhanced solar-driven photocatalytic performance

Autor: Ran Duan, Jiufu Chen, Junbo Zhong, Shengtian Huang, Jianzhang Li

Publikováno v: Inorganic and Nano-Metal Chemistry. :1-12

Ag3PO4/BiPO4 composite photocatalysts were constructed by a precipitation method. The composites were studied by Brunauer -Emmett-Teller (BET), X-ray diffraction patterns (XRD), UV-Vis diffuse refl...

A comprehensive gas extraction system coupling high-level suction roadway and boreholes for gas disaster prevention in closely-spaced multiple coal seams

Autor: Jiufu Chen, Zhaolong Ge, Liang Cheng, Feng Yang, Lishuang Zou, Hongbo Lei

Publikováno v: Energy Sources, Part A: Recovery, Utilization, and Environmental Effects. :1-14

Mining a protective layer is an effective way to prevent coal and gas outbursts in underground coal mines; this method has been used widely. However, when mining closely spaced multiple coal seams ...
