A:

Do slower moving particles create more thrust in space? When using explosives a slow detonation velocity is best when it comes to moving dirt. 

In a vacuum, no. There is no external material you can push around. 
The property you're looking for is detonation velocity: the speed of the shockwave as it travels through the explosive. 

If fragmentation is desired, the best results are obtained when the detonation velocity is at or near the sonic velocity of the rock. If mass movement is more important (as in blast casting) or very large fragments are desired (as in riprap production or slabbing), detonation velocity should be notably below the rock's sonic velocity.

So this is about transferring the energy from the explosive to the surrounding material.
In a rocket engine (of any type in use today), there is no surrounding material. The propellant does not push anything else along. In fact, you want the exhaust speed to be as high as possible. The efficiency of a rocket is expressed as its specific impulse, basically the amount of acceleration you can get out of a set amount of propellant. 
$$I_{sp} = \frac{V_e}{g_0}$$
Isp = specific impulse
Ve = exhaust velocity
g0 = standard (Earth) gravity
The effect does happen in the atmosphere. 
Turbojet engines are inefficient at low aircraft speeds, because the exhaust speed is not matched well to the speed of the surrounding air. Early jet aircraft needed really long runways because of this. 
Turbofan engines take most of the energy from the turbine exhaust and use it to drive a low-speed fan. This means there's a much better match between exhaust speed and the speed of the surrounding air. 
Responding to Nathan's comment: 

Everything about this answer is correct except for the first line. If there was a way to slow exhaust without outright wasting all the extra energy, it absolutely would increase thrust. Power, thrust, and specific impulse are all directly related, and maintaining the same exhaust power at a lower specific impulse guarantees higher thrust. This is the principle behind the VASIMR's high- and low-"gear" modes.

VASIMR has two modes, they work like this:

accelerate a small amount of propellant to a high speed (for high efficiency, but low thrust)
use the same

 Do slower move particle create more thrust in space? When use explosives a slow explosion velocity is best when it comes to affect dirt. 

 In a vacuum, no. There be no external material you can push round. 
 The place you're looking for is detonation speed: the speed of the shockwave as it travel through the explosive. 

 If fragmentation is desired, the best results are prevail when the detonation velocity is at or near the sonic velocity of the rock candy. If mass movement is more important (as in blast casting) or very big fragments are desired (as in riprap production or slabbing), detonation velocity should be notably below the rock's sonic velocity. 

 So this is about transferring the energy from the explosive to the surrounding material. 
 In a rocket engine (of any type in use today), there is no surround material. The propellant does not push anything else along. In fact, you desire the exhaust focal ratio to be equally high as possible. The efficiency of a rocket is expressed as its specific impulse, basically the amount of acceleration you can get out of a set sum of propellant. 
 $ $ I_{sp } = \frac{V_e}{g_0}$$ 
 Isp = specific impulse 
 Ve = exhaust velocity 
 g0 = standard (Earth) gravity 
 The effect does find in the atmosphere. 
 Turbojet engines are inefficient at low aircraft speeds, because the exhaust speed is not matched well to the focal ratio of the surrounding air. Early jet aircraft needed really retentive runways because of this. 
 Turbofan engines take most of the department of energy from the turbine exhaust and use it to repel a low - speed sports fan. This means there's a much better match between exhaust speed and the focal ratio of the surrounding breeze. 
 Responding to Nathan's remark: 

 Everything about this answer is right except for the first line. If there was a room to slow exhaust without instantaneously wasting all the extra energy, it absolutely would increase stab. Power, thrust, and specific impulse are all directly related, and keep the same exhaust power at a lower specific urge guarantees higher thrust. This is the principle behind the VASIMR's high- and low-"gear " modes.
