不同培肥处理对采煤塌陷地复垦土壤生化作用强度及玉米产量的影响
Shuitu Baochi Xuebao, 2011 利用不同培肥处理对晋城采煤塌陷区复垦土壤微生物生化作用强度及玉米产量进行研究,结果表明:当每个培肥处理施入等量的氮(N)、磷(P2O5)时,有机肥+化肥+菌肥处理的氨化、纤维素分解作用强度好于其余处理且在复垦第3年达到最高,与有机肥+化肥差异显著;单施有机肥的硝化作用强度最大,与有机肥+化肥+菌肥处理差异不明显;对照的固氮作用强度最大与其余处理差异显著;有机肥+化肥+菌肥的产量高于其余处理,有机肥+化肥次之,除有机肥+化肥+菌肥与有机肥差异显著外,其余差异都不显著;氨化、硝化 ...

工程建设, 2023 小康煤矿位于康平煤田的东北部，隶属康平县东关镇。矿井自投产以来，截止2021年未已先后在北一、西一、南一、南二采区及西三采区共回采了33个工作面。其中，有25个工作面采用的综合机械化一次采全高放顶煤开采方法，煤层最大采出厚度达14.3m（含2煤）。大范围地下煤层开采产生了严重的地表沉陷，雨季沉陷区大面积积水。尤其是在采用综放开采的区域，地表最大下沉达4.5～6.5m，部分塌陷坑常年积水。目前西三采区是2019年经过辽宁省自然资源厅依法由大平煤矿采区边界划归到小康开采边界。w3轨道运输大巷，巷道断面宽4 ...
