The control of the deep - seated structural - magmatic process over the metallogenic system around the middle - lower yangtze river reaches is shown as : ( 1 ) the mantle uplift belt is closely related to the general geological background of the metallogenic system ; ( 2 ) the primitive magma originated from different parts of the mantle uplift belt ( mantle ridge or mantle slope ) shows differences in style of formation and composition and results in different magmatic series and metallogenic subzones, respectively ; ( 3 ) the varying depths of structural - magmatic chambers may form a " three - layered structure " ( central type, network - like and ring - like ) and this is the primary factor that controls the different magmatic series and the concerned cluster of ore deposits ; ( 4 ) the alkaline basaltic magma derived from the mantle ridge forms high - potassium and calcium alkaline magma and shoshonitic magma due to its altering intensity of afc process with the lower crustal material, which has something to do with the copper - gold and iron - sulphur metallogenic subsystems, respectively
深部構造巖漿作用對長江中下游成礦帶安徽沿江地區成礦系統的控製表現為： （ 1 ）地幔隆起帶與成礦系統的總體地質背景的演變密切相關； （ 2 ）源於地幔隆起帶不同部位（幔脊與幔坡）的原始巖漿，其生成方式和物質組成不盡相同，它們分別產生相應的不同巖漿巖系列和成礦亞帶； （ 3 ）不同深度的構造巖漿房組成中心式網格式環帶式「三層結構」 ，是控制區內不同巖漿巖系列及有關礦床集中分佈的主要因素； （ 4 ）源於地幔隆起帶脊部的堿性玄武巖漿，由於與下地殼物質發生的afc作用強度不同，形成了高鉀鈣堿性巖漿和橄欖安粗巖漿，分別與銅、金成礦亞系統和鐵、硫成礦亞系統有關。 -
Based on the engineering practice of the side slope excavation of dayanchi section within the road for the construction traffic of guandi hydropower station, the problems such as the selection of blasthole distance for presplit blasting, and the rock ridge, the levelness of the presplit face, lower hole - making rate of the auxiliary blastholes after the presplit blasting, the blasting network for prespliting and blasting zone and the angle change of the presplit hole etc. are analyzed ; for which the specific solutions are put forward herein as well
摘要通過官地水電站對外交通公路大鹽池合同段邊坡開挖中預裂爆破的工程實踐，對預裂爆破的孔距選擇及下部嚴重出現巖坎、預裂面平整度、預裂爆破后輔助孔成孔率低、預裂與爆破區爆破網路以及預裂孔角度變化等問題進行分析，提出了具體的解決方法。
