豫西煤田勘探施工区处于低山丘陵、山前坡地,卵石、砾岩层密布,潜水位深或无潜水等困难的地震地质条件,难以钻井至潜水面下放炮。坑炮又得不到有效反射波,在有耕地处采用多个浅井(砾岩面以上)组合放炮,对农作物损害严重。这使地震勘探工 The exploration and construction area in western Henan coalfield is difficult to drill down to the surface of the submerged area due to difficult geological conditions such as low hills, hillside slopes, pebbles, conglomerate layers, deep or no diving. In addition, there is no effective reflected wave in the pit gun. In combination with multiple shallow wells (above the conglomerate surface) in arable land, the crop is seriously damaged. This makes the seismic explorer
