Key technologies of efficient extraction of coalbed methane (gas) in Guizhou coal mine area by Wang YI, Longjun LIANG, Lichong YAN, Zhihua YAN, Jie CHEN, Wei GAO, Yi LOU, Fuqin YANG, Haiyang HU, Jiawei ZHU

“…It innovated and explored the following high efficiency extraction technology of “four zones” linked Wells in coal mining areas with Guizhou characteristics: ① By laying multi-functional pumping vertical Wells or small inclination oriented Wells in the goaf, it was the first time in Guizhou to realize efficient extraction and development of pressure relief gas in the overlying coal-covered strata and coal-bed methane in the sweet coal seam below the goaf; ② Taking advantage of the characteristics of spatial and temporal dislocation in the production area, the multi-mode extraction mode of “coalbed methane well + relief well + underground drilling” is adopted for the first coal seam mined in the upper protective layer, which realizes the purpose of the upper and lower vertical combined extraction of coalbed methane (gas) Wells and effectively solves the problem of multi-source gas flooding into coal mining roadway and gas accumulation in the upper corner during coal mining under the condition of coal seam group development in Guizhou; ③ In the preparation area and planning area, combined with the terrain and geological characteristics of the two areas, the horizontal well “well factory” + “two pairs of right and wrong” overlapping well layout mode is adopted to realize the efficient extraction of coal bed methane in the plane in advance and pre-pumping of the sweet coal seam and the pressure relief gas in the overlying coal-laden rock in the subsequent mining process, and at the same time to achieve the goal of “replacing the roadway with Wells”; ④ In view of the development of multi-thin coal seam groups in the study area and the development characteristics of “three zones” in the overlying strata after mining, due to the continuous change of the role of “four zones”, the surface coalbed methane Wells are initially deployed in the production area or preparation area, and the “bridge plug bottom sealing + layer selection perforation” technology is adopted to innovate the “transformation” technology of well structure to achieve the purpose of “multi-purpose in one well”; It also provides new technical ideas and accumulated valuable engineering experience for gas management in coal mine area under the condition of multi-thin coal seam group development in Guizhou.…”

Phonological and Sociolinguistic Challenges of Translating Yorùbá Play, and Game Songs to Singable English for Children by Bolanle O. Sogunro

“…Consequently, the translations are “unperformable” as oral texts, thus, failing their aesthetic and functional purpose for children. To investigate the translation problems involved and proffer solutions, this essay analyses five randomly selected Yoruba songs and seven of their available English translations from online sources and an unpublished manuscript, using sociolinguistic translation theory and the analytical framework of Franzon’s song translation choices. …”
