Striker Glover scored 19 goals for the Pitmen last season and took on the role of caretaker manager while new owners Graham Jones and Hayden Dando completed their takeover of the club.
Alongside his playing duties, Glover has also been appointed assistant manager to boss Andy Morrell.
Goalkeeper Wycherley enjoyed two impressive loan spells at the PRG Stadium last season – joining on a temporary basis from Solihull Moors.
He has now agreed a 12-month deal with a further year’s option with the Pitmen.
Meanwhile, the club have reduced the price of season tickets for fans buying through the early bird scheme. An adult season ticket costs £150 with concessions £110. Season tickets are £75 for for under 18s and £25 for junior Pitmen members.
