put this where you declare variables:

private int[][] MinePos = { { 2845, 2968, 0 }, { 2838, 2970, 0 },
                        { 2832, 2970, 0 }, { 2829, 2983, 0 }, { 2824, 2997, 0 } };


put this anywhere:

public boolean WalkAlongPath(int[][] path, boolean AscendThroughPath,
                        int distanceFromEnd) {
                if (distanceToPoint(AscendThroughPath ? path[path.length - 1][0]
                                : path[0][0], AscendThroughPath ? path[path.length - 1][1]
                                : path[0][1]) <= distanceFromEnd)
                        return true;
                else {
                        WalkAlongPath(path, AscendThroughPath);
                        return false;
                }
        }

        public void WalkAlongPath(int[][] path, boolean AscendThroughPath) {
                int destination = 0;
                for (int i = 0; i < path.length; i++)
                        if (distanceToPoint(path[i][0], path[i][1]) < distanceToPoint(
                                        path[destination][0], path[destination][1]))
                                destination = i;
                if (client.getMyPlayer().isMoving()
                                && distanceToPoint(path[destination][0], path[destination][1]) > (isRunning() ? 3
                                                : 2))
                        return;
                if (AscendThroughPath && destination != path.length - 1
                                || !AscendThroughPath && destination != 0)
                        destination += (AscendThroughPath ? 1 : -1);
                try {
                        log("Walking to node:" + destination);
                        walk(new Position(path[destination][0], path[destination][1], 0));
                        Thread.sleep(700 + MethodProvider.random(600));
                } catch (InterruptedException e) {
                        e.printStackTrace();
                }
        }

        private int distanceToPoint(int pointX, int pointY) {
                return (int) Math.sqrt(Math
                                .pow(client.getMyPlayer().getX() - pointX, 2)
                                + Math.pow(client.getMyPlayer().getY() - pointY, 2));
        }


put this where you want to execute the walk:

try {
                        WalkAlongPath(MinePos, true);
                } catch (Exception localException) {
                }
