| 摘 要： | 跟着煤层顶板或底板施工的采区煤巷,底板坡度变化有时较大,要掌握、准确地计算底板坡度,必须实测出底板坡度变化各特征点的标高,采用常规方法有时完成很困难,为此提出一种新的观测方法bh法,从50 m范围以内或以外两个方面三种情况,分别阐述bh法在实际中的具体运用,从而表明bh法观测采区煤巷底板坡度是切实可行的.

| Abstract: | When going along with the start construction of the coal steam's roof of bottom board, the coal alley of pick district sometimes has relatively big changes in its slope of bottom board. To correctly calculate the slope of bottom board, efforts should be made to measure the elevation of all the trait points. It is very difficult to finish the measurement by common approaches; therefore, a new observation approach named "bh" is put forward. The concrete practice of this approach is presented in three situations and in two aspects inside or outside 50 meters, thus enunciating that this approach is practically feasible. |
