改善煤炭工业生产的条件之一是在相对井田边界合理地布置巷道的基础上进一步改善采区的回采工艺及采用有效的支护方法。随着采深的增大,巷道支护的条件变得日趋复杂,特别是在回采煤层群时这一课题更具有现实意义。
One of the conditions for improving the coal industry’s production is to further improve the mining process and adopt effective supporting methods based on the rational arrangement of roadways at the minefield boundary. With the increase of mining depth, the conditions of roadway support become more and more complicated, especially in the mining of coal seams this issue more practical significance.
