| 摘 要： | 从可靠性的角度，应用强度分布和应力分布的干涉理论，对综放工作面移架—割煤系统的可靠性进行了较为详细的分析，并建立了相应的联结方程，得到了采支速度比的计算公式.计算结果表明，采支速度比随系统可靠度的变化可分为3个明显不同的范围，不同类型的工作面应按照不同的可靠度要求选取相应的数值.对于高产高效综放面，采支速度比应在1.30～1.50范围内选取；对超长综放面，采支速度比应在1.50～1.80范围内选取.图2，表2，参6.

| Abstract: | From the angle of reliability, the system of coal cutting and support moving of high productivity and efficiency work face is analyzed in detail by using the interference theory of strength and stress distribution. The coupling equation and calculation formulas of the velocity ratio of coal cutting to support moving are established. The characteristic curve of the velocity ratio consists of three different areas, so the ratio of different work face should be selected according to different demand of reliability. The velocity ratio of coal cutting to support moving can be selected from 1.3 to 1.5 in high productivity and efficiency work face, or from 1.5 to 1.8 in super-length fully mechanized top-coal caving face.2figs.,2tabs.,6refs. |
