Ask your administrator to import the data locally, or you could break it into 30 parts and import each one.
If all of the inserts are each on one line, you could parse the file line by line (or get the entire file and explode by insert but don't forget to add insert back to the beginning of the query when you run).
Then do each individual mysql_query($querystring).
If doing this way, have an if statement around it like so
if (mysql_query($query)){ //success
}else{echo $query."<br>";}
so you'll have a record of what queries did not commit and can save them to perform later.
