  We give a uniform description of resolvents and complex powers of elliptic
semiclassical cone differential operators as the semiclassical parameter $h$
tends to $0$. An example of such an operator is the shifted semiclassical
Laplacian $h^2\Delta_g+1$ on a manifold $(X, g)$ of dimension $n\geq 3$ with
conic singularities. Our approach is constructive and based on techniques from
geometric microlocal analysis: we construct the Schwartz kernels of resolvents
and complex powers as conormal distributions on a suitable resolution of the
space $[0,1)_h\times X\times X$ of $h$-dependent integral kernels; the
construction of complex powers relies on a calculus with a second semiclassical
parameter. As an application, we characterize the domains of
$(h^2\Delta_g+1)^{w/2}$ for $\mathrm{Re}\,w\in(-\frac{n}{2},\frac{n}{2})$ and
use this to prove the propagation of semiclassical regularity through a cone
point on a range of weighted semiclassical function spaces.
