岩爆因其严重危及施工人员与设备的安全,影响施工进展,以致在现代化国防施工,长大隧道的兴建,水利地下洞室的开凿,以及矿山深部采掘等方面,作为一种特殊的工程地质现象,愈来愈引起人们对它的重视.(一)几座铁路山岭隧道在施工中发生岩爆的实况在成昆铁路北段的关村坝、乌斯河、塔足古等几座隧道中,在施工时发生过岩爆.程度虽有所异,但情况大致相同.在开挖断面围岩压 Rock blasting is a special type of engineering geology because it seriously jeopardizes the safety of construction personnel and equipment, and affects the progress of construction, leading to the construction of modern national defense, the construction of long tunnels, the excavation of water conservancy underground caverns, and the deep mining of mines. Phenomenon, more and more people pay attention to it. (A) the actual situation of rock burst in the construction of several railway mountain tunnels in the northern section of the Cheng-Kun Railway Guancunba, Uusu River, Tagu ancient several tunnels In the construction, rock bursts occurred during construction. Although the degree is different, but the situation is roughly the same. In the excavation section, the surrounding rock pressure
