山西沁水煤田范围内有3#、9#、15#三层可采煤层，部分矿井由于规划井田范围内相互之间存在不同程度的上下层位重叠的情况，晋煤集团海天煤业与寺河二号井就属于这种情况。同时由于寺河二号井开采速度快已经将海天煤业9#和15#开采，为了确保海天煤业3#煤层的安全开采，本文对已采区的上覆煤层安全开采作了初步的探索。

There are three minable seams of 3#, 9#, 15#in the range of Shanxi Qinshui coalfield, the existence of different degrees of stratigraphic overlap between part of the mine during the planning, JinCheng Coal Group Haitian coal and Sihe No.2 well belongs to this situation. At the same time due to the fast mining speed, the Sihe No. 2 well has mined the under group 9# and 15#, in order to ensure mining safety of coal seams in coal 3# Haitian. In this paper, makes a preliminary exploration of the upward mining technology.
