  In this paper, we are dealing with a new type of Baskakov-Schurer-Szasz
operators (\ref{eq1}). Approximation properties of this operators are explored:
the rate of convergence in terms of the usual moduli of smoothness is given,
the convergence in certain weighted spaces is investigated. We study
$q$-analogues of Baskakov-Schurer-Sz\'{a}sz operators and it's Stancu
generalization. In the last section, we give better error estimations for the
operators (\ref{eq2}) using King type approach and obtained weighted
statistical approximation properties for operator (\ref{qb})
