浅释缓倾斜煤层底板采动破坏深度与回采参数关系

Talking about relation between the destruction depth of floor mining at flately inclined seam and actual mining parameters

介绍了采面斜长、采高与底板采动破坏深度的关系 ,查明厚煤层分层开采时 ,底板破坏程度主要取决于第一分层 。

The relations between the inclined face length,mining height and floor mining destruction depth are analyzed.It shows the floor destruction degree is briefly controlled by the first branch layer when layer mining.It provides a basis for reforming coal mining with safe band pressure.
