矿山井下安装设备的硐室,多是属于新开凿出的空间。底板岩石抗压强度远比人为混凝土抗压强度高。只要在裸露的岩石表面上适当进行人工处理,就是比较理想的矿山井下天然设备基础。适宜把设备锚固在这个基础上。 (一)井下设备锚固基础的特征矿山普遍采取凿岩爆破的方法开凿井下机电设备硐室。除光面爆破外,常用的爆破方法都会给硐室壁造成一定范围的裂缝区;同时硐室 Underground mine equipment installation chamber, mostly belonging to the new cut out of space. Bottom rock compressive strength is far higher than the compressive strength of artificial concrete. As long as the bare rock surface properly handled, it is the ideal mine base of natural equipment. Suitable for anchoring the equipment on this basis. (A) the characteristics of underground equipment anchoring foundation Mining generally take the method of rock blasting drilling underground mechanical and electrical equipment room. In addition to smooth blasting, the commonly used blasting method will cause a range of cracks in the chamber wall; at the same time chamber
