新汶矿区禹村煤矿二号井东翼一、三采区的二、三层煤于1959～1960年进行了回采。但自1962年以来,位于采区上山方向按移动角圈定的开采影响范围以外的杜村庄民房不断发生裂缝和变形,甚至有11间房屋产生倒塌。如果按照房屋破坏的范围来确定上山移动角,则该角值仅在13°～23°之间。这种情况的出现对该矿区来说是异常的。类似的情况还发生在肥城矿区曹庄矿和杨庄矿井田范围内的尚古庄和乔庄。为了查清这些破坏的原因,我们对禹
The second and third layers of coal in the first and third mines in the east wing of No.2 well of Yucun Coal Mine in Xinwen Mining Area were recovered from 1959 to 1960. However, since 1962, Ducunzhuang houses located outside the mining area affected by the mining angle in the ascending direction of the mining area continued to crack and deform. As a result, 11 houses collapsed. If the range of housing damage to determine the moving angle of the mountain, the angle value is only between 13 ° ~ 23 °. The appearance of this situation is abnormal for this mining area. A similar situation also occurred in the Feicheng mine Caozhuang mine and Yangzhuang mine field within the range of ancient Gu Zhuang and Qiao Zhuang. In order to find out the cause of these damage, we Yu
