为了使各种形式的正二测和正三测从理论研究转向实际应用，克服长期来人们在绘制轴测图时，多数只能采用正等测和斜二测等单调情况，以及提高绘图速度，本文推荐采用七种正二测和三种正三测，并设计一套绘制这十种正轴测的专用工具--轴测多角比例尺。本文提出一套近似作这十种正轴测坐标面上椭圆的方法和数据，使其既简便又准确。

Through similar simulation test of block top-coal drawing, the influence of coal block size and block position in top coal on the recovery ratio and drawing manner is studied. It is found that the drawing manner has the different adaptation to the top coal which has different block distribution. The caving capacity is mainly decided by the block size. The top-coal which has layer difference of block with the same size has different recovery ratio. It is shown, that, to the given top-coal blocks, the recovery ratio of uniformly mixed blocks is maximal in the manner of drawing at interval of one support.

研究表明，顶煤块体大小是影响顶煤回收效果的主要因素，在顶煤块径一定的条件下，块体层位分布不同是造成顶煤回收率差异的主要原因，研究表明各级块度均匀混合时顶煤回收效果最好，块度从下向上增大分布次之，大块为中位顶煤时回收效果最差；各种放煤方式的适应性不同，各级块度均匀混合的顶煤适合用间隔放煤；块度从下向上增大适合用顺序放煤；大块在顶煤中位分布时，中硬煤以下适合用间隔放煤，硬煤应采用顺序放煤方式。
