| 中文摘要 |
| 嵩山煤矿区有两层主要可采煤层(石炭系的一1煤和二迭系的二1煤),在同一矿井采用相同的采煤设备和采煤工艺,当开采一1煤层时,几乎不产生煤尘,当开采二1煤层时,煤尘污染却十分严重.因二1煤层在未开采前就遭到了嵩山巨型滑动构造的强烈挤压和揉磨,煤层结构和构造被破坏,使之成为颗粒细小的粉末状,为煤尘产生的物质条件.一1煤层因未受滑动构造影响,使其结构构造完整如初.因此,嵩山地区以及受滑动构造影响的相邻或其它地区煤尘产生的主要原因应该是滑动构造对煤层的破坏程度. |
| 英文摘要 |
| In the Mount Song coal mining area, there are two main minablecoal seams-the carboniferous system Tai Yuan group's coalseam(Ⅰ) and the permian system San Xi group's coal seam(Ⅰ) Through the same mining installations and technology are used in a pit,the coal dust produced is very different.During the mining of coal seam(Ⅰ) .there is little coal dust,while during the mining of coal seam(Ⅱ)serious pollution of coal dust is poduced.The reason is that coal seam (Ⅱ) has been vigorously pressed and kneaded by the Mount Song glide tectonics and the composition and construction of the seam has been destroyed resulting in the formation of powdery coal.However,coal seam(Ⅰ) was not influenced by the glide tectonics, thus the composition and constrction of the seam were not destroyed.Therefore it can be inferred that the primal cause for the formation of coal dust in the referred areas is the destruction of coal seam. |
