Testing research of coal layer safe extraction in efflorescent oxygenized belts 風氧化帶內煤層安全開采的試驗研究
The following new opinions : without caving zone coal layer extraction in efflorescent oxygenized belts ; two effects of blocking water and preventing water flowing fractured zone from going on developing after mining effect ; appropriately enlarging the extraction thickness were presented 提出了風氧化帶煤層開采無垮落帶;受采動影響后,具阻水和抑制導水裂隙帶繼續發展的雙重作用以及適當加大開采厚度等新觀點。
Based on testing data in worksite and engineering practice , the strata damage movement characteristics , rock properties of weathered zone and qualitative and quantitative analysis of the mechanism of coal layer safety extraction in efflorescent oxygenized belts were discussed 摘要根據現場觀測和工程實踐,論述了風氧化帶內煤層開采時,覆巖破壞移動特征,風化帶巖石屬性和風氧化帶內煤層安全開采機理的定性、定量分析。
But the grain growth , grain semiconduction and grain boundary insulation were influenced by many factors , such as the type and contents of dopants , sintering temperature and so on . therefore , in this thesis the effect of the restore sintering temperature , the oxygenize temperature , the donor and acceptor dopant on the dielectric and varistor properties of devices were studied . with sem , the microstructure of srtio3 - based double function ceramic was analyzed 而晶粒生長、晶粒半導化和晶界絕緣化受到多種因素的影響,諸如雜質的種類和含量、燒成溫度等,因此本論文研究了還原燒成溫度、中溫氧化溫度、施主和受主摻雜等對srtio _ 3基陶瓷的壓敏和介電性能的影響,并借助于sem分析對srtio _ 3基雙功能陶瓷的微觀結構進行了分析。
