How to select specific value on join condition?

I have a table that contains the details of a game, this table is called match, each match can have n goals, these goals are stored inside the table goal.

Suppose I have the following situation on match:

id = 2564824
home_team_half_time_score = 2
home_team_score = 4
away_team_half_time_score = 0
away_team_score = 0

so this record means that the match is ended 4 - 0 for the home team, what I want to know is: how can I get only the goals scored in the first time? in this case there are 2 goals scored in the first time, and have this id:

id    | match_id | result | minute 
16092   2564824    1 - 0     15
16093   2564824    2 - 0     43
16094   2564824    3 - 0     63
16095   2564824    4 - 0     78

I just need to get the minute field of each goal, how can I setup the query?

Thanks for any help.

UPDATE

actual query:

$query = "SELECT m.*,
  t.name AS team_name,
  t.id AS team_id,
  l.position AS team_rank,
  COUNT(CASE WHEN g.type = 5 THEN 1 END) AS failed_to_score,
  FROM `match` m
  LEFT JOIN goal g ON m.id = g.match_id
  LEFT JOIN team t ON t.id = :team_id
  LEFT JOIN league_ranking l ON l.team_id = :team_id AND l.round_id = :round_id
  WHERE m.round_id = :round_id
  AND m.status = 5 ";

SELECT minute, result FROM goal WHERE (CAST(minute AS UNSIGNED)<=45 OR minute like '45%') AND match_id='2564824'

if this is your starting point:

id    | match_id | result | minute 
16092   2564824    1 - 0     15
16093   2564824    2 - 0     43
16094   2564824    3 - 0     63
16095   2564824    4 - 0     78

If this is indeed your expected results then you have to show the input data to get this result

UNTESTED

SELECT m.*,
  t.name AS team_name,
  t.id AS team_id,
  l.position AS team_rank,
  COUNT(CASE WHEN g.type = 5 THEN 1 END) AS failed_to_score,
  g.minute
  FROM `match` m
  LEFT JOIN goal g ON m.id = g.match_id
  LEFT JOIN team t ON t.id = :team_id
  LEFT JOIN league_ranking l ON l.team_id = :team_id AND l.round_id = :round_id
  WHERE m.round_id = :round_id
  AND m.status = 5 "
  AND (CAST(minute AS UNSIGNED)<=45 OR minute like '45%');

This integrated query will stop the analysis of each match to the first half. I'd keep the two queries as separate
