摘要
巷道放顶煤是急倾斜中厚—厚煤层安全、高效开采的一种新方法 .应用模糊数学和灰色理论 ,建立模型确定顶煤初采松动高度 ,经试验证明是合理的、可行的 .
On the basis of analysis of the factos affected on loose height of the roadway caving coal for mining the steep medium?thickness and high seam,the evaluating function and decising model are established by fuzzy mathematics and grey decision theory.The loose height of crown coal is determined.The practice has proved that the model is reasonable and feasible.
