部分萃取
偏提取
Examples
- Manage of rock burst in mine with great mining depth partial extraction and strong roof face
煤层采场顶板活动变化及综采面支护强度初探 - Standard practice for preparation of natural - matrix sediment reference samples for major and trace inorganic constituents analysis by partial extraction procedures
使用部分萃取法的大量和微量无机成分分析用天然杂矿石沉淀物标样制备的标准实施规范 - The effect of overburden separation dynamic development under key stratum on grouting for bed separation space was analyzed , in order to deal with the problem that the current bed separation growing technology can not prevent the key stratum from breakage , put forward the isolated section - grouting technology for overburden bed separation space , integrated the virtue of growing for bed separation space and partial extraction , the bed separation grouting bodies , key stratum and isolated section pillars were made to constitute the load - carrying body all together , and to reach the purpose of reducing subsidence effectively , increase the coal seam extraction ratio , and accelerate the development of isolated section - growing technology for overburden bed separation space
摘要分析了关键层下离层动态发育对离层充填的影响，针对目前离层区充填工艺不能阻止覆岩关键层初次破断的问题，提出了“覆岩离层分区隔离注浆充填”技术，它综合离层充填与条带开采技术的优点，通过离层区充填置换或减小分区隔离煤柱宽度，使“离层区充填体关键层分区隔离煤柱”形成共同承载体，从而达到有效减缓地面沉降的目的，提高了煤层采出率，促进了覆岩离层充填减沉技术的发展。 - The predication technical methods consist of experience - analogy , geochemical techniques ( e . g . geo - gas method and partial extraction of mobile forms ) , geophysical techniques ( e . g . radioactivity survey , ground electromagnetism , earthquake technique , hole geophysical survey ) , remote sensing , gis , and comprehensive information prognosis methods
