Spatial charge
From Memory Alpha, the free Star Trek reference.
A spatial charge is an projectile weapon fired from a starship and designed to explode at a certain distance from the target. Smaller versions can also be used as bombs.
In the 22nd century, the MACOs employed spatial charges against planet-based installations, in which the charges' effects can be focused with blast suppressors placed on the surface. Major Hayes wanted to use two spatial charges to destroy a kemocite mining facility on a Xindi-Arboreal colony, though he was overruled by Captain Jonathan Archer. (ENT: "The Shipment")
The USS Voyager deployed spatial charges like mines in a battle against the Kazon in 2372. (VOY: "Relativity")
Malon export vessel, eleventh gradients are armed with spatial charges. (VOY: "Night")
The crew of USS Voyager used spatial charges to disable the primary shield generator of a Borg sphere in 2375, as part of their plan to steal a Borg transwarp coil. (VOY: "Dark Frontier")
Later that year, the Voyager crew planted spatial charges in a debris field to disable a Hazari vessel. They also used modified spatial charges to force the Think Tank vessel out of subspace. (VOY: "Think Tank")
