Chain Reaction with Arrays and Distance - arrays

Question

I want to make a program in which mines will appear on the screen after a user inputs the number of mines. Then, the user will click on one mine and set off a chain reaction that explodes the nearest two mines.
So far, my code can prompt the user for the number of mines, and then display them. The mines are buttons in which, when clicked, will be removed and an explosion will appear.
However, I am stuck with how I can handle the chain reaction. I am relatively new to coding in AS3 and therefore am stumped with no clue on how to approach this part of my program.
Code:
package
{
import flash.display.MovieClip;
import flash.text.TextField;
import flash.text.TextFieldType;
import flash.events.*;
public class Minefield extends MovieClip
{
var integer:int;
var iField:TextField = new TextField();
var button:iButton = new iButton();
var i:int;
var mines:Array = new Array();
public function Minefield()
{
var explosion:iExplosion = new iExplosion();
iField.type = "input";
iField.height = 18;
iField.x = 460;
iField.y = 275;
iField.border = true;
iField.restrict = "0-9";
iField.maxChars = 2;
stage.focus = iField;
addChild(iField);
addChild(button);
button.x = 450;
button.y = 175;
button.buttonMode = true;
button.addEventListener(MouseEvent.CLICK, UponClick);
}
function AddMines()
{
for (i = 0; i < integer; i++)
{
CreatorOfMine();
mines[i].addEventListener(MouseEvent.CLICK, UponMineClick)
mines[i].buttonMode = true;
}
}
function CreatorOfMine()
{
mines[i] = new Mine();
MineLocation()
}
function MineLocation()
{
mines[i].x = Math.round(Math.random() * 925);
mines[i].y = Math.round(Math.random() * 525);
mines[i].rotation = Math.random() * 360;
addChild(mines[i]);
}
function UponClick(e:MouseEvent)
{
integer = int(iField.text);
RemoverOfChildren();
}
function RemoverOfChildren()
{
removeChild(button);
removeChild(iField);
AddMines();
}
function UponMineClick(event:MouseEvent){
var mineObject:Mine = Mine(event.currentTarget)
var expl:iExplosion = new iExplosion()
expl.x = mineObject.x
expl.y = mineObject.y
expl.rotation = mineObject.rotation
addChild(expl)
removeChild(mineObject)
}
}
}
}
Information you may need/want:
Stage size is 1024 x 600 (px)
Size of mine(s) is 40 x 40 (px)
Size of explosion is 40 x 40 (px)

Looks like a good case for recursion. Pseudo-code:
Function ExplodeMine(mine) {
mine.boooooooooom()
nearest = findNearestUnexplodedMines()
foreach(nextMine in nearest) {
ExplodMine(nextMine);
}
}
Just start ExplodeMine on the first mine that is clicked.
