I want to predict the blockometry of blocks of rock after slaughter

I have a problem, I want to use the neural networks in the prediction of the fragmented block percentage after felling and I can not really do it, all I see is the prediction of a series of times

so I have 5 input parameters and one output which is fragmented block size.

what I understood about the process is that I have trained the network with known inputs and outputs and then enter the parameters that I want to predict but I do not know how to do,

I need a little program if possible.

I need your help please
