Try this:

#+PROPERTY: header-args :tangle-mode (identity #o444)
#+PROPERTY: header-args+ :tangle no
#+PROPERTY: header-args+ :mkdirp yes
#+PROPERTY: header-args+ :exports both
#+PROPERTY: header-args+ :comments both
#+PROPERTY: header-args+ :padline yes
#+PROPERTY: header-args+ :eval no-export
#+PROPERTY: header-args:R :session *R_proMixStands*

#+BEGIN_SRC R 
2 + 2
#+END_SRC

#+BEGIN_SRC emacs-lisp
(defun tj/get-property-values ()
  (interactive)
  (let (lst)
    (org-element-map (org-element-parse-buffer) 'keyword
      (lambda (--kw)
	(when (equal (org-element-property :key --kw) "PROPERTY")
	  (let ((val (org-element-property :value --kw)))
	    (setq lst
		  (cons (split-string val " :" t) lst))))))
    lst))
#+END_SRC

#+results:
: tj/get-property-values

#+BEGIN_SRC emacs-lisp :results table
(tj/get-property-values)
#+END_SRC

#+results:
| header-args:R | session *R_proMixStands*     |
| header-args+  | eval no-export               |
| header-args+  | padline yes                  |
| header-args+  | comments both                |
| header-args+  | exports both                 |
| header-args+  | mkdirp yes                   |
| header-args+  | tangle no                    |
| header-args   | tangle-mode (identity #o444) |
