村庄下科学采煤的研究与探讨

科学合理地开采村庄下压煤是新老矿区提高经济、社会效益的重要问题,也是煤矿开采技术中探讨的重要理论和实践问题。村庄下采煤可用条带法开采、充填法开采、长壁多工作面协调开采、全柱式开采、极不充分开采法、双翼背向开采、村庄维护或建抗变形结构新村等七种开采方法。这七种开采方法各有其优势,也各有其劣势,应结合每个煤矿的具体情况和经济、技术条件,扬长避短。

Investigation of Mining under Village in a Scientific Way

Mining under village in a scientific and rational way is an important issue for boosting economic and social benefits for new and old mining areas; meanwhile, it's also a crucial theoretical and practical issue concerning coal mining technology. Seven mining methods can be adopted in mining under village, namely, strip method, filling method, coordinated longwall multi-working-face mining, stoop method, super-subcritical mining, bi-wing raise mining, village maintenance or building of new deformation-resistant village, each with respective advantages and disadvantages, thus the adoption should be in line with the specific economic and technological conditions within a specific mine.
