Subject: Please Help: Recursion and Array Problem (Noob)

The explanation of what I'm trying to do are noted in the comments...
I'm freakin' lost... the really big issue is determining how to test
mines that have been blown up against remaining
mines... you'll find that comment smack dab in the middle...

today is the first day I've ever used Ruby, I appreciate the help:

## Load data from file into Python
mines_data = file.open('example_mines.txt', 'r')

## function to determine if a mine blows up another mine
def within_blast_radius(x1, y1, blast_radius, x2, y2)
  ((x1 - x2) ** 2 + (y1 - y2) ** 2) <= (blast_radius ** 2)
end

## define variables to keep track of outputs
qty_mines_blown = 0
max_mines_blown = 0

## define a multidimensional  array with x number of rows and 3 columns
master_array = array.new(r) {Array.new(3)}
cnt = 0
starting_mine = master_array [cnt]
# For Each Mine do this:
master_array.each = {|r|
    # within_blast_radius(x1, y1, bomb_radius, x2, y2)  ## Tests to see
if bomb x1, y1 blows up bomb x2, y2
    master_array.each{|r|
    if within_blast_radius(master_array[cnt][1], master_array[cnt][2],
master_array[cnt][3], master_array[r][1], master_array[r][2]) = True
        qty_mines_blown += 1
        ## code to test mines that have been blown up against remaining
mines
    endif
    }
    if qty_mines_blown > max_mines_blown
        max_mines_blown = qty_mines_blown
        answers_array.delete
        answers_array[0] = starting_mine
    elseif qty_mines_blown = max_mines_blown
        answers_array.next_line = starting_mine
    endif
    cnt += 1
    }
print "The maximum number of mines that can be blown up from triggering
just one mine is: "
print max_mines_blown
print "The location and blast radius of mine(s) that can trigger the
blast is :"
print elements in answers_array
