苏联技术科学副博士的《风钻轴压力的计算》一文,收在煤炭工业出版社1958年3月出版的《钻眼爆破》一书中。该文无视凿岩机、钎子和岩石的相互作用,企图只从凿岩机自身的孤立运动中推导出轴推力公式。如我们已经证明的(见《凿岩机最佳轴推力的研究》,《煤炭科学技术》1980年第10期),当水平位置的凿岩机空转时,它不需要任何轴推力,重心的位置始终保持不变。所由出发的概念显然是错误的。如果
Soviet Union, vice president of science and technology, “wind drill shaft pressure calculation,” a text, received in the coal industry publishing house in March 1958 published “drilling blasting” in a book. Ignoring the interaction between rock drill, braze and rock, this paper attempts to derive the axial thrust formula only from the isolated movement of the rock drill. As we have already shown (see “Study on Optimum Axial Thrust of Drilling Rigs”, “Coal Science and Technology”, Issue 10, 1980), a rock drill in a horizontal position does not require any axial thrust and the center of gravity remains unchanged change. The rationale for the departure is obviously wrong. in case
