unloaded hole

Factors,such as diameter size of injection holes on trees,diameter size of injector blowholes,trees species,trunk basal diameter and season changes,which might affect the absorption to 4% Imidacloprid liquid formulation(ILF)by trees,were analyzed with auto flowing trunk injection.

采用4%吡虫啉注干液剂,研究自流式注药过程中注药孔孔径、注药器通气孔孔径、树种、树干基径及季节等因素对药剂吸收的影响。

Four aspects,namely,the system of developing,effects of wide space blasting,shape of blasting area and single-hole charge,which should be paid attention to in the design of open medium-depth hole bench cut blasting,are put forward in this paper.

根据作者的实际工作经验,提出了露天台阶深孔爆破设计中应注意的4个问题:1)开拓系统建设关系到土石方工程的布局,影响工程成本和进度,应予以足够重视;2)采用正三角形布孔,斜线起爆,即可取得小抵抗线宽孔距的爆破效果;3)爆区形状以长方形或平行四边形为好,长宽比应大于3;4)单孔药量计算应综合考虑爆破参数之间的逻辑关系。
