摘　　要：以内蒙古包头市黄河磴口段开河前冰盖为试验对象,采用2#岩石乳化炸药,集中药包型式,炸药量分别为8、10、12kg三种,在冰盖下部不同入水深度处进行水中爆破破冰。通过对试验点冰厚、药包入水深度和破冰效果的量测,得到了集中药包在相同药量下,药包入水深度与爆破破冰体积的关系。研究了相同重量的集中药包在不同入水深度条件下的破冰效果,得出了在炸药重量、药包入水深度等优化参数组合条件下,爆炸能量才能得到充分利用,爆破破冰效果达到最佳的结论。By taking the ice sheet as research object in Dengkou section of the Yellow River, Baotou, Inner Mongolia. The ice breaking experiments in different depths under the ice sheet were conducted by using concentrated charge of 2# rock emulsion explosive with three weight levels of 8kg, 10kg and 12kg. Through the measurement of ice thickness, the depth of charge in the water and the effect of ice breaking, the relation between the depth of charge in the water and ice breaking volume under same weight of con- centrated charges condition were obtained. The effects of ice breaking of the same weight charge in different water depths were also analyzed. The conclusion showed that the explosion energy could be made full use of and the effect of ice breaking could achieve optimization under combination of optimal parameters condi- tions such as the weight and the depth of charge in the water.
