地下运输巷道支护的经济性表现在不同支护方法上。坑木支护广泛使用并成为开拓巷道的基本方法,但也有木支架与钢支架结合或与砌旋相结合等。原来支护型式的被破坏,就要求考虑新的型式——具有对y轴与x轴同样的较大的抗弯强度。回答这个问题之一是土斯萨因特一海因滋曼 Toussaint-Heint mann设计支架,即一般说的T.H支架。 The economy of underground transportation roadway support is manifested in different support methods. Hanging timbering is widely used and has become the basic method to open up the roadway, but there are also wooden brackets combined with steel brackets or the combination of rotary and others. The original type of support is destroyed, it is required to consider the new type - with the y-axis and x-axis of the same larger bending strength. One of the questions to answer is the Toussaint-Heintmann design bracket for Tusset-Heinzman, the so-called T.H stent.
